Program Id: TODO
Description: To-Do Reminder List
Programmer: David Cook - Cookware
Welcome to Version 1.0 of TODO, a To-Do list reminder system. This program
was written for a friend of mine who refused to buy a HP48SX unless it had
a TODO program, scheduler (with calendar) and Rolodex (he would rather have
a HP48SX instead of a Wizard etc.., but needed that functionality). Since I
already have a rolodex and calendar program for my 48SX I only needed to
provide this function.
Disclaimer:
I have had my 48SX only about 3 months, so I am sure that this program can
be written better, smaller and faster. I would have used SYSEVAL statements,
but was unsure about compatibility with other revisions (can anyone out there
answer this question?).
Shareware Notice:
Feel free to use this program and redistribute it. I ask that if you
redistribute the program, please keep it named TODO, and please keep the
title screen intact. If you make significant changes, please add you name
to the title screen - but keep my name as well. If you find this program
invaluable, a $5 donation would be appreciated. Send any money or comments
to: David Cook, RR #1 Box 351, Whitestown Indiana 46075 - Thank you!
Installing And Running TODO:
The program can be found at the bottom of this post. It is in ->ASC format
and you will need ASC-> to unscramble it. ASC-> is openly available on this
forum as well as the HP BBS. (The ASC routines were written by Bill Wickes.)
I'm sure that if you don't have them, an open letter to the NET would produce
them rather quickly!
(1) Cut the code at the bottom of the document, AFTER the CUT HERE line.
Remove the final CUT HERE line at the bottom.
(2) Send this file to your HP48SX, via the Serial Cable, into the file 'TODO'
(3) Hit the TODO button (eg., place the contents of TODO on the command line)
(4) Execute ASC-> (which you already should have loaded, or load it now)
(5) Store the result back to 'TODO' - it will become a directory
Running...
(6) Simply enter the TODO directory and hit the RUN button which will be
the very first button you see.
From here on out, simply follow (6) to run it.

* Ability to MARK and UNMARK items on the list
* Ability to UNMARK ALL items on the list
* Ability to delete any single item on the list
* Ability to delete ALL MARKED items on the list
* Ability to insert a new item anywhere in the list
* Ability to sort any list of information
GROCERY LIST
I have created a large (though somewhat incomplete) grocery lists, as a
default. It is large so it does take a bit of time to compile the GROB. Use
this list as an example list, and delete it if you need the memory or find it
unusable.
How To Use TODO
---------------
When the program begins to run, it will display six menu items assigned
to the menu keys. These six items are:
LIST - Catalog of all lists OR create a new list OR delete a list
ADD - Adds a new item to the end of the list OR inserts a blank item
EDIT - Edits the text of an existing item
SORT - Sort any particular list
MARK - Marks an item OR Unmarks an item OR Unmarks all marked items
EXIT - Exits the program and returns you to the HOME directory
The following lists the available KEYSTROKES from the main menu level:
UP ARROW - Scroll the current list towards the top - one item
ORANGE SHIFT UP ARROW - Move the current list toward the top - one page
BLUE SHIFT UP ARROW - Move the current list to the top
DOWN ARROW - Scroll the current list toward the bottom - one item
ORANGE SHIFT DOWN ARROW - Move the current list toward the bottom - one page
BLUE SHIFT DOWN ARROW - Move the current list to the bottom
DEL (keyboard key) - Deletes the current item
ORANGE SHIFT DEL (purge)- Deletes ALL marked items
LIST (menu key) - Get a catalog of all lists
BLUE SHIFT LIST - Enter the name for a brand new list
ADD (menu key) - Add an item to the end of the current list
BLUE SHIFT ADD - Insert a blank line ABOVE the current item
EDIT (menu key) - Edit the text of the current line
SORT - Sort the current list in alphabetical order
MARK (menu key) - Mark OR Unmark the current item
BLUE SHIFT MARK - Unmark ALL marked items
ORANGE SHIFT MARK - Same as MARK without the Startrek sound
EXIT - Stop the program and return to the HOME directory
BLUE SHIFT EXIT - Turn the calculate off (turning it on returns to
TODO automatically with no delay)
Here are some general comments about a couple of the commands...
CURRENT ITEM
The current item (eg., the item you are going to MARK, UNMARK, DELETE etc..)
is the one at the TOP OF THE DISPLAY. To move an item into the current item
area, simply scroll (UP/DOWN arrow) until it is the top item on the list. This
goes for catalog lists (LIST) as well.
LIST
When in LIST, all current lists in the current directory will be displayed, in
alphabetical order (eg., sorted). WHILE you are in this mode, UP and DOWN
arrow work (but PAGE UP and PAGE DOWN and GO TO TOP and GO TO END do not work).
The DEL keyboard key will DELETE a list completely from memory.
MARK
The MARK command allows you to place a marker next to items which you have
completed (eg., check 'em off). Hit MARK the first time to place the marker,
Hit MARK a second time (on the same item) to unmark. When you MARK or UNMARK
a 'startrek' type beep will occur to signify the mark. If you do not wish
to hear the sound, hit ORANGE SHIFT MARK instead. BLUE SHIFT MARK will UNMARK
ALL currently marked entries WITHOUT deleting them from the list.
DEL
The normal 48SX DEL key serves to DELETE the current item, when hit under
the normal menu (when hit while in LIST, it deletes entire lists). If you
hit ORANGE SHIFT DEL, the program will delete ALL marked entries - useful
for purging information you have already done.
STARTING UP
If you start the program, and the current list is not found by the program
(eg., you deleted it from the operating system level), the LIST command will
automatically be run by the program. If the LIST command does not see any
lists in memory, the BLUE SHIFT LIST command will automatically be run, allowing
you to create a new list.
OTHER KEYBOARD KEYS
If you hit an unknown key (eg., not known to the program), the program will
issue a very low tone. Try again!
Internals:
This posting is already too long to give you full details of the program.
Feel free to rip it apart and improve it - just post it back! One routine
you will probably want to add to your 'favorites' list is the routine named
R2D2. This, standalone, routine takes a single number from the stack and
makes your HP48SX sound like a device on Star Trek. The best values, for
the most convincing sound are the values 4 or 5. Simply type
5 R2D2
for a demo. The number indicates the length of time (eg., number of chirps)
for the speaker to make).
Another routine you will find useful is the SORT routine. To use SORT
independently of the program, simply place a LIST of STRINGS on Level 1 and
run SORT. This is NOT a bubble sort, but an insertion sort, and it only takes
as long to sort the data as it does to read the data one time (plus the linear
count to find the place to put the data).
Other items you will find useful, if reverse engineering the routines... The
variable 'DATA' contains the name of the current to-do list database. The
system creates TEMPORARY variables (only will be seen if you abort the program
while it is running). 'W' contains a number which signifies which item is
the current iten (1 - S). 'S' contains the total number of items in the list.
If you abort during a catalog, you will see CATTEMP which contains a list of
all you to-do lists. 'W', 'S' and 'CATTEMP' are all deleted and rebuilt
by the program.
Here is a brief listing of what the other routines do:
RUN - Runs the TODO program
SORT - Sorts a LIST of STRINGS in level 1
MON - High speed GROB editor, used to turn a Mark ON
MOFF - High speed GROB editor, used to turn a Mark OFF
INSTD - INSerts a blank item into the ToDo list above the current item
EDITD - EDIts the current item of the current ToDo list
NEWTD - Creates a NEW ToDo list
CATTD - Handles the LIST command catalog of lists
SEETD - Displays the current list (does NOT build it)
MAKTD - Makes the GROB associated with the current list
ADDTD - Adds a new item to the END of the current list
MARTD - Handles Marking and Unmarking of the current item
UNMTD - Unmarks ALL marked items in the list
WIPTD - Deletes ALL marked items in the list
DELTD - Deletes the current item in the list
R2D2 - Takes a repeat value from level 1 and issues StarTrek sounds
AGAIN... these routines should only be used for editing and changing the
program. Use the RUN routine to execute the program (just hit RUN) and the
program will automatically issues these routines for you in responce to the
menu keys you hit (as described above). I provided the details above only
for those who want to see how it runs!
ENJOY!!!!!

In case other people have the same comments, I'm posting my comments here rather than sending them directly to you. Just in case this wouldn't get to you otherwise, I'm also mailing this directly to your email address. Please let me know if you're interested in making the below changes. If not, I will make them myself, and can send them back to you (for a repost by one of us). > Installing And Running TODO: > How To Use TODO > When the program begins to run, it will display six menu items assigned > to the menu keys. These six items are: > LIST - Catalog of all lists OR create a new list OR delete a list I found the list screen confusing because I couldn't figure out how to add or delete lists until I read through all the instructions. It might be a little more intuitive if the LIST screen provided the add and delete as function keys. By the way, when I created a new list, I tried to use the name "WORK-TODO" and it aborted the program (probably the "-" is an illegal variable name. You might want to check the variable names for validity before trying to use them. Also, having delete list be a single keystroke (DEL) without confirmation seems dangerous. I could wipe out a large amount of data by accident with a single button. How about a confirmation question ("Really Delete" with a default -- already in the input buffer of "no".) > DEL (keyboard key) - Deletes the current item Again, a confirmation would be nice. Actually, I'd be happy with just disabling the DEL key completely and requiring MARK followed by PURGE to do any delete (since it's two keystrokes, it's unlikely to happen by mistake, especially since PURGE requires a shift key as well. > BLUE SHIFT LIST - Enter the name for a brand new list If this were a function key in the LIST screen, it wouldn't require a separate keystroke to remember. > EDIT (menu key) - Edit the text of the current line It would be great if you would include the original contents of the item in the input buffer so editing would not always require a complete retype for minor changes. I believe it's just a variant on the INPUT command. > BLUE SHIFT EXIT - Turn the calculate off (turning it on returns to > TODO automatically with no delay) How about defining BLUE SHIFT ON to have this function instead? That way it would be the normal OFF function with nothing special to remember. Also, how about defining ON/ATTN to be the same as EXIT, so if that key is accidentally hit, everything is left in a clean state. This would be especially nice if it worked in all contexts. > Here are some general comments about a couple of the commands... > When you MARK or UNMARK > a 'startrek' type beep will occur to signify the mark. If you do not wish > to hear the sound, hit ORANGE SHIFT MARK instead. BLUE SHIFT MARK will UNMARK This is just a small cosmetic suggestion, but why not have some sort of toggle instead which controls whether the beep happens or not? If the toggle state were maintained in a variable in the directory, then it would be persistent and people wouldn't have to type extra keys regardless of which they preferred. > OTHER KEYBOARD KEYS > If you hit an unknown key (eg., not known to the program), the program will > issue a very low tone. Try again! > 'W', 'S' and 'CATTEMP' are all deleted and rebuilt by the program. I don't have my manual handy right now so I can't check this, but I think if you use lower case letters for the local variables, they will be deleted when the function exits thus avoiding the cleanup problem (if you need them in several functions, this may not work for you, though). Is there a font as small as the one you use which can display both upper and lower case? It's (mildly) annoying to get everthing displayed in upper case when I typed it in in lower case. By the way, where is the font set (so I can change it to one that displays lower case if I want to)? Please don't interpret these comments as critical. I'm really glad you wrote and posted this program. It's extremely close to what I've been looking for for a few months (and haven't had the time to write myself). If you agree with the suggestions but don't have time to do some of them, I'll do them myself and send them back. Anyway, thanks for the great new tool!

If not, > I will make them myself, and can send them back to you (for a repost by one > of us). I decided to go ahead and make some of the changes. I will post a new copy (ASC format) in another couple days when I finish the changes. The changes I've made so far are the following: Made the OFF key turn the calculator off while in TODO (instead of BLUE SHIFT [EXIT]) Made the [EDIT] menu key return the current text as the default value for the new text (which also makes it easy to cancel an edit simply by pressing ENTER without making any changes). Made the program font-size independent (with a table for the font sizes for the 3 builtin available fonts) and provided a binding (+ and - keys) for dynamically changing the size of the font while the program is running. I did this because the small font is good when you want lots of data, but is hard on the eyes since it's all uppercase, so I want different fonts at different times (depends on how wide the data is I'm viewing. Implemented horizontal scrolling (by character, 10 characters at a time, and beginning and end of line). I also increased the width of the GROB to 2 screens (adjustable with a local variable in the TODO directory). I also would like to change the LIST mode to be function key driven like the normal interface, but haven't implemented that yet. In addition, I'd like to trap the ATTN key using Bill Wickes IFERR routine. I'll post either when I get all the changes finished or I expect it to be awhile before I get the rest done (I'll probably post in a couple of days). > > 'W', 'S' and 'CATTEMP' are all deleted and rebuilt by the program. > I don't have my manual handy right now so I can't check this, but I think > if you use lower case letters for the local variables, they will be deleted > when the function exits thus avoiding the cleanup problem (if you need them > in several functions, this may not work for you, though). Sorry, I was confused. I withdraw the suggestion. The lower versus upper case issue is just convention. Local variables will only work if the variables are not shared between functions and they are, so they won't address this problem.

Program Id: TODO
Description: To-Do Reminder List
Programmer: David Cook - Cookware
Modified: John Diamant (modifications version 1.0)
This program is a generic list manager for the 48SX calculator. It
works not only on todo lists, but any other type of list you care to
manage in the calculator (limited by memory of the calculator).
I'm not going to repeat most of the general announcements from the original
posting as I'm including it at the bottom of this message. Please note in
particular the shareware notice in David's original comments.
Installation instructions are the same as the original (see David's note
at the bottom if you don't know how to install an ASC format program).
If you can't download via ASC and need a cleartext posting (translate
code 3), let me know (email would be fine) and I'll post that as well.
However, to avoid further delay, I'm posting this now in ASC format.
If you use this new TODO version and like it, I'd like to hear from
you (especially if you're using the new features I added to it). If anybody
knows David Cook's email address, I'd like to get in touch with him
to merge my changes into his master version.
The next response to this note will be a question I have regarding
memory efficiency and PICT. If I find out how to improve the memory
efficiency, I'll probably post a modified version, so you'll have to decide
whether you want to wait or download this version. However, the lists you
build with this version should work just fine for a more memory efficient
version and I may be able to provide a simple patch (by the way, the
memory usage problem is not something I introduced with my changes but my
increasing the width of the PICT made it more likely to occur).
To run the program, simply press the RUN button in the variables menu in
the TODO directory (I use the following entry in my CST menu to start up the
program: { "LIST" << TODO RUN >> })
By the way, I have truncated the grocery list substantially from the
originalposting due to it's taking too much space. If you want the full one,
download
the original posting.
The changes from David's version 1.0 are as follows:
Made the OFF key turn the calculator off while in TODO (instead of BLUE
SHIFT [EXIT])
Made the [EDIT] menu key return the current text as the default value for
the new text (which also makes it easy to cancel an edit simply by
pressing ENTER without making any changes).
Made the program font-size independent (with a table for the font sizes
for
the 3 builtin available fonts) and provided a binding (+ and - keys)
for dynamically changing the size of the font while the program is
running. I did this because the small font is good when you want
lots of data, but is hard on the eyes since it's all uppercase, so I
want different fonts at different times (depends on how wide the
data is I'm viewing.
Implemented horizontal scrolling (by character, 10 characters at a time,
and beginning and end of line). I also increased the width of the
virtual screen (adjustable with a local variable in the TODO
directory).
LIST mode (choose which list to make active) has been extended to support
USE, NEW, and DEL menu buttons rather than requiring obscure
keystrokes for these functions.
Made LIST mode more robust (added beeps for incorrect keystrokes).
Deleting a list asks for confirmation (default is no).
Changed the keybinding for deleting an item from a list from DEL to
BLUE SHIFT DEL to avoid risk of accidental deletion.
The ATTN key is trapped via IFERR and appropriate cleanup is done
(note that I do not rely on Bill Wickes special version of IFERR --
the builtin was sufficient for my purpose -- to make sure the
program cleaned up if I accidentally used ATTN instead of EXIT)
Disables clock display during program execution and restores initial
state of clock (displayed or not) on exit (even with ATTN key).
Made the function which create new lists do some error checking on legal
names (using "V" mode for INPUT).
Removed reordering of vars on exit to put RUN at beginning since I
run the program from CST and I don't want to pay the run-time cost
every time I exit to reorder the VARS menu.

Sorry it was more than a couple of days, but I think you'll be glad I waited
as I did add some functionality almost each day I delayed posting.
How To Use TODO (modified from David's original instructions)
---------------
When the program begins to run, it will display six menu items assigned
to the menu keys. These six items are:
LIST - Catalog of all lists OR create a new list OR delete a list
ADD - Adds a new item to the end of the list OR inserts a blank item
EDIT - Edits the text of an existing item
SORT - Sort any particular list
MARK - Marks an item OR Unmarks an item OR Unmarks all marked items
EXIT - Exits the program and returns you to the HOME directory
The following lists the available KEYSTROKES from the main menu level:
UP ARROW - Scroll the current list towards the top - one item
ORANGE SHIFT UP ARROW - Move the current list toward the top - one page
BLUE SHIFT UP ARROW - Move the current list to the top
DOWN ARROW - Scroll the current list toward the bottom - one
item
ORANGE SHIFT DOWN ARROW - Move the current list toward the bottom - one page
BLUE SHIFT DOWN ARROW - Move the current list to the bottom
LEFT ARROW - scroll the current list towards the left - one char
ORANGE SHIFT LEFT ARROW - scroll the current list towards the left - 10
charsBLUE SHIFT LEFT ARROW - scroll the current list to the left edge
RIGHT ARROW - scroll the current list towards the right - one char
ORANGE SHIFT RIGHT ARROW- scroll the current list towards the right - 10
chars
BLUE SHIFT RIGHT ARROW - scroll the current list to the right edge
BLUE SHIFT DEL - Deletes the current item
ORANGE SHIFT DEL (purge)- Deletes ALL marked items
LIST (menu key) - Get a catalog of all lists
BLUE SHIFT LIST - Enter the name for a brand new list (also
available in LIST environment as function key)
ADD (menu key) - Add an item to the end of the current list
BLUE SHIFT ADD - Insert a blank line ABOVE the current item
EDIT (menu key) - Edit the text of the current line
SORT - Sort the current list in alphabetical order
MARK (menu key) - Mark OR Unmark the current item
BLUE SHIFT MARK - Unmark ALL marked items
ORANGE SHIFT MARK - Same as MARK without the Startrek sound
EXIT - Stop the program and return to the HOME directory
BLUE SHIFT ON (OFF) - Turn the calculate off (turning it on returns to
TODO automatically with no delay)
+ - Increase font to next larger size
- - Decrease font to next smaller size
KEYSTROKES available from LIST screen (entered via LIST menu key):
UP ARROW - Scroll the current list towards the top - one item
DOWN ARROW - Scroll the current list toward the bottom - one
item
USE (menu key) - make top list on screen currently viewed list
ENTER - same as USE
NEW (menu key) - Create new list (same as BLUE SHIFT LIST above)
DEL (menu key) - Delete top list on screen (will ask for confirmation)
+ - Increase font to next larger size
- - Decrease font to next smaller size
Note the setting of PW below to change the width of your virtual screen.
The one I posted is set to 200 but you might prefer 262 (2 screens)if
you have sufficient memory.
New Internals (see the original posting for other internals):
Here is a brief listing of what the other routines do:
PW - page width. Number of pixels of width to make the PICT display.
The screen is 131 wide, so use no less than 131, but larger than
131 is required to get any horizontal scrolling.
EXIT - function used to clean up and exit (called from a few places)
CHFONT - takes delta for font number as argument and sets up CHARH,
CHARW, FONT, and H for selected font. Values of 1, -1, and 0
are useful (increase font size by one, decrease font size by one,
and set up font attributes for initialization respectively)
FNTATTR - list containing font attributes (width and height in pixels) for
the 3 builtin fonts. Note that the list is stored as a string
and converted on the fly to avoid it being seen by the TODO program
as a user-specified list.
CHARH - character height in pixels of currently selected font
CHARW - character width in pixels of currently selected font
H - number of items which can be displayed on one screen in
current font
FONT - number of currently selected font (used in ->GROB call)
Only PW should be changed by a user of the program. The rest are only
documented if you want to change the program. They are managed internally.

Program Id: TODO
Description: To-Do Reminder List
Programmer: David Cook - Cookware
Welcome to Version 1.0 of TODO, a To-Do list reminder system. This program
was written for a friend of mine who refused to buy a HP48SX unless it had
a TODO program, scheduler (with calendar) and Rolodex (he would rather have
a HP48SX instead of a Wizard etc.., but needed that functionality). Since I
already have a rolodex and calendar program for my 48SX I only needed to
provide this function.
Disclaimer:
I have had my 48SX only about 3 months, so I am sure that this program can
be written better, smaller and faster. I would have used SYSEVAL statements,
but was unsure about compatibility with other revisions (can anyone out
thereanswer this question?).
Shareware Notice:
Feel free to use this program and redistribute it. I ask that if you
redistribute the program, please keep it named TODO, and please keep the
title screen intact. If you make significant changes, please add you name
to the title screen - but keep my name as well. If you find this program
invaluable, a $5 donation would be appreciated. Send any money or comments
to: David Cook, RR #1 Box 351, Whitestown Indiana 46075 - Thank you!
Installing And Running TODO:
The program can be found at the bottom of this post. It is in ->ASC
formatand you will need ASC-> to unscramble it. ASC-> is openly available
on this
forum as well as the HP BBS. (The ASC routines were written by Bill Wickes.)
I'm sure that if you don't have them, an open letter to the NET would
producethem rather quickly!
(1) Cut the code at the bottom of the document, AFTER the CUT HERE line.
Remove the final CUT HERE line at the bottom.
(2) Send this file to your HP48SX, via the Serial Cable, into the file '
TODO'
(3) Hit the TODO button (eg., place the contents of TODO on the command
line)
(4) Execute ASC-> (which you already should have loaded, or load it now)
(5) Store the result back to 'TODO' - it will become a directory
Running...
(6) Simply enter the TODO directory and hit the RUN button which will be
the very first button you see.
From here on out, simply follow (6) to run it.

GROCERY LIST
I have created a large (though somewhat incomplete) grocery lists, as a
default. It is large so it does take a bit of time to compile the GROB.
Usethis list as an example list, and delete it if you need the memory or
find it
unusable.
How To Use TODO
---------------
When the program begins to run, it will display six menu items assigned
to the menu keys. These six items are:
LIST - Catalog of all lists OR create a new list OR delete a list
ADD - Adds a new item to the end of the list OR inserts a blank item
EDIT - Edits the text of an existing item
SORT - Sort any particular list
MARK - Marks an item OR Unmarks an item OR Unmarks all marked items
EXIT - Exits the program and returns you to the HOME directory
The following lists the available KEYSTROKES from the main menu level:
UP ARROW - Scroll the current list towards the top - one item
ORANGE SHIFT UP ARROW - Move the current list toward the top - one page
BLUE SHIFT UP ARROW - Move the current list to the top
DOWN ARROW - Scroll the current list toward the bottom - one
item
ORANGE SHIFT DOWN ARROW - Move the current list toward the bottom - one page
BLUE SHIFT DOWN ARROW - Move the current list to the bottom
DEL (keyboard key) - Deletes the current item
ORANGE SHIFT DEL (purge)- Deletes ALL marked items
LIST (menu key) - Get a catalog of all lists
BLUE SHIFT LIST - Enter the name for a brand new list
ADD (menu key) - Add an item to the end of the current list
BLUE SHIFT ADD - Insert a blank line ABOVE the current item
EDIT (menu key) - Edit the text of the current line
SORT - Sort the current list in alphabetical order
MARK (menu key) - Mark OR Unmark the current item
BLUE SHIFT MARK - Unmark ALL marked items
ORANGE SHIFT MARK - Same as MARK without the Startrek sound
EXIT - Stop the program and return to the HOME directory
BLUE SHIFT EXIT - Turn the calculate off (turning it on returns to
TODO automatically with no delay)
Here are some general comments about a couple of the commands...
CURRENT ITEM
The current item (eg., the item you are going to MARK, UNMARK, DELETE etc..)
is the one at the TOP OF THE DISPLAY. To move an item into the current item
area, simply scroll (UP/DOWN arrow) until it is the top item on the list.
This
goes for catalog lists (LIST) as well.
LIST
When in LIST, all current lists in the current directory will be displayed,
in
alphabetical order (eg., sorted). WHILE you are in this mode, UP and DOWN
arrow work (but PAGE UP and PAGE DOWN and GO TO TOP and GO TO END do not
work).
The DEL keyboard key will DELETE a list completely from memory.
MARK
The MARK command allows you to place a marker next to items which you have
completed (eg., check 'em off). Hit MARK the first time to place the marker,
Hit MARK a second time (on the same item) to unmark. When you MARK or
UNMARKa 'startrek' type beep will occur to signify the mark. If you do not
wish
to hear the sound, hit ORANGE SHIFT MARK instead. BLUE SHIFT MARK will
UNMARK
ALL currently marked entries WITHOUT deleting them from the list.
DEL
The normal 48SX DEL key serves to DELETE the current item, when hit under
the normal menu (when hit while in LIST, it deletes entire lists). If you
hit ORANGE SHIFT DEL, the program will delete ALL marked entries - useful
for purging information you have already done.
STARTING UP
If you start the program, and the current list is not found by the program
(eg., you deleted it from the operating system level), the LIST command will
automatically be run by the program. If the LIST command does not see any
lists in memory, the BLUE SHIFT LIST command will automatically be run,
allowing
you to create a new list.
OTHER KEYBOARD KEYS
If you hit an unknown key (eg., not known to the program), the program will
issue a very low tone. Try again!
Internals:
This posting is already too long to give you full details of the program.
Feel free to rip it apart and improve it - just post it back! One routine
you will probably want to add to your 'favorites' list is the routine named
R2D2. This, standalone, routine takes a single number from the stack and
makes your HP48SX sound like a device on Star Trek. The best values, for
the most convincing sound are the values 4 or 5. Simply type
5 R2D2
for a demo. The number indicates the length of time (eg., number of chirps)
for the speaker to make).
Another routine you will find useful is the SORT routine. To use SORT
independently of the program, simply place a LIST of STRINGS on Level 1 and
run SORT. This is NOT a bubble sort, but an insertion sort, and it only
takes
as long to sort the data as it does to read the data one time (plus the
linear
count to find the place to put the data).
Other items you will find useful, if reverse engineering the routines...
Thevariable 'DATA' contains the name of the current to-do list database.
Thesystem creates TEMPORARY variables (only will be seen if you abort the
program
while it is running). 'W' contains a number which signifies which item is
the current iten (1 - S). 'S' contains the total number of items in the
list.
If you abort during a catalog, you will see CATTEMP which contains a list of
all you to-do lists. 'W', 'S' and 'CATTEMP' are all deleted and rebuilt
by the program.
Here is a brief listing of what the other routines do:
RUN - Runs the TODO program
SORT - Sorts a LIST of STRINGS in level 1
MON - High speed GROB editor, used to turn a Mark ON
MOFF - High speed GROB editor, used to turn a Mark OFF
INSTD - INSerts a blank item into the ToDo list above the current item
EDITD - EDIts the current item of the current ToDo list
NEWTD - Creates a NEW ToDo list
CATTD - Handles the LIST command catalog of lists
SEETD - Displays the current list (does NOT build it)
MAKTD - Makes the GROB associated with the current list
ADDTD - Adds a new item to the END of the current list
MARTD - Handles Marking and Unmarking of the current item
UNMTD - Unmarks ALL marked items in the list
WIPTD - Deletes ALL marked items in the list
DELTD - Deletes the current item in the list
R2D2 - Takes a repeat value from level 1 and issues StarTrek sounds
AGAIN... these routines should only be used for editing and changing the
program. Use the RUN routine to execute the program (just hit RUN) and the
program will automatically issues these routines for you in responce to the
menu keys you hit (as described above). I provided the details above only
for those who want to see how it runs!
ENJOY!!!!!

Program Id: TODO
Description: To-Do Reminder List
Programmer: David Cook - Cookware
Modified: John Diamant (modifications version 1.0)
This program is a generic list manager for the 48SX calculator. It
works not only on todo lists, but any other type of list you care to
manage in the calculator (limited by memory of the calculator).
I'm not going to repeat most of the general announcements from the original
posting as I'm including it at the bottom of this message. Please note in
particular the shareware notice in David's original comments.
Installation instructions are the same as the original (see David's note
at the bottom if you don't know how to install an ASC format program).
If you can't download via ASC and need a cleartext posting (translate
code 3), let me know (email would be fine) and I'll post that as well.
However, to avoid further delay, I'm posting this now in ASC format.
If you use this new TODO version and like it, I'd like to hear from
you (especially if you're using the new features I added to it). If anybody
knows David Cook's email address, I'd like to get in touch with him
to merge my changes into his master version.
The next response to this note will be a question I have regarding
memory efficiency and PICT. If I find out how to improve the memory
efficiency, I'll probably post a modified version, so you'll have to decide
whether you want to wait or download this version. However, the lists you
build with this version should work just fine for a more memory efficient
version and I may be able to provide a simple patch (by the way, the
memory usage problem is not something I introduced with my changes but my
increasing the width of the PICT made it more likely to occur).
To run the program, simply press the RUN button in the variables menu in
the TODO directory (I use the following entry in my CST menu to start up the
program: { "LIST" << TODO RUN >> })
By the way, I have truncated the grocery list substantially from the original
posting due to it's taking too much space. If you want the full one, download
the original posting.
The changes from David's version 1.0 are as follows:
Made the OFF key turn the calculator off while in TODO (instead of BLUE
SHIFT [EXIT])
Made the [EDIT] menu key return the current text as the default value for
the new text (which also makes it easy to cancel an edit simply by
pressing ENTER without making any changes).
Made the program font-size independent (with a table for the font sizes for
the 3 builtin available fonts) and provided a binding (+ and - keys)
for dynamically changing the size of the font while the program is
running. I did this because the small font is good when you want
lots of data, but is hard on the eyes since it's all uppercase, so I
want different fonts at different times (depends on how wide the
data is I'm viewing.
Implemented horizontal scrolling (by character, 10 characters at a time,
and beginning and end of line). I also increased the width of the
virtual screen (adjustable with a local variable in the TODO
directory).
LIST mode (choose which list to make active) has been extended to support
USE, NEW, and DEL menu buttons rather than requiring obscure
keystrokes for these functions.
Made LIST mode more robust (added beeps for incorrect keystrokes).
Deleting a list asks for confirmation (default is no).
Changed the keybinding for deleting an item from a list from DEL to
BLUE SHIFT DEL to avoid risk of accidental deletion.
The ATTN key is trapped via IFERR and appropriate cleanup is done
(note that I do not rely on Bill Wickes special version of IFERR --
the builtin was sufficient for my purpose -- to make sure the
program cleaned up if I accidentally used ATTN instead of EXIT)
Disables clock display during program execution and restores initial
state of clock (displayed or not) on exit (even with ATTN key).
Made the function which create new lists do some error checking on legal
names (using "V" mode for INPUT).
Removed reordering of vars on exit to put RUN at beginning since I
run the program from CST and I don't want to pay the run-time cost
every time I exit to reorder the VARS menu.
> I'll post either when I get all the changes finished or I expect it to be
> awhile before I get the rest done (I'll probably post in a couple of days).
Sorry it was more than a couple of days, but I think you'll be glad I waited
as I did add some functionality almost each day I delayed posting.

ENTER - same as USE
NEW (menu key) - Create new list (same as BLUE SHIFT LIST above)
DEL (menu key) - Delete top list on screen (will ask for confirmation)
+ - Increase font to next larger size
- - Decrease font to next smaller size
Note the setting of PW below to change the width of your virtual screen.
The one I posted is set to 200 but you might prefer 262 (2 screens)if
you have sufficient memory.
New Internals (see the original posting for other internals):
Here is a brief listing of what the other routines do:
PW - page width. Number of pixels of width to make the PICT display.
The screen is 131 wide, so use no less than 131, but larger than
131 is required to get any horizontal scrolling.
EXIT - function used to clean up and exit (called from a few places)
CHFONT - takes delta for font number as argument and sets up CHARH,
CHARW, FONT, and H for selected font. Values of 1, -1, and 0
are useful (increase font size by one, decrease font size by one,
and set up font attributes for initialization respectively)
FNTATTR - list containing font attributes (width and height in pixels) for
the 3 builtin fonts. Note that the list is stored as a string
and converted on the fly to avoid it being seen by the TODO program
as a user-specified list.
CHARH - character height in pixels of currently selected font
CHARW - character width in pixels of currently selected font
H - number of items which can be displayed on one screen in
current font
FONT - number of currently selected font (used in ->GROB call)
Only PW should be changed by a user of the program. The rest are only
documented if you want to change the program. They are managed internally.

---------------------- original (unmodified) announcement from David --------
Program Id: TODO
Description: To-Do Reminder List
Programmer: David Cook - Cookware
Welcome to Version 1.0 of TODO, a To-Do list reminder system. This program
was written for a friend of mine who refused to buy a HP48SX unless it had
a TODO program, scheduler (with calendar) and Rolodex (he would rather have
a HP48SX instead of a Wizard etc.., but needed that functionality). Since I
already have a rolodex and calendar program for my 48SX I only needed to
provide this function.
Disclaimer:
I have had my 48SX only about 3 months, so I am sure that this program can
be written better, smaller and faster. I would have used SYSEVAL statements,
but was unsure about compatibility with other revisions (can anyone out there
answer this question?).
Shareware Notice:
Feel free to use this program and redistribute it. I ask that if you
redistribute the program, please keep it named TODO, and please keep the
title screen intact. If you make significant changes, please add you name
to the title screen - but keep my name as well. If you find this program
invaluable, a $5 donation would be appreciated. Send any money or comments
to: David Cook, RR #1 Box 351, Whitestown Indiana 46075 - Thank you!
Installing And Running TODO:
The program can be found at the bottom of this post. It is in ->ASC format
and you will need ASC-> to unscramble it. ASC-> is openly available on this
forum as well as the HP BBS. (The ASC routines were written by Bill Wickes.)
I'm sure that if you don't have them, an open letter to the NET would produce
them rather quickly!
(1) Cut the code at the bottom of the document, AFTER the CUT HERE line.
Remove the final CUT HERE line at the bottom.
(2) Send this file to your HP48SX, via the Serial Cable, into the file 'TODO'
(3) Hit the TODO button (eg., place the contents of TODO on the command line)
(4) Execute ASC-> (which you already should have loaded, or load it now)
(5) Store the result back to 'TODO' - it will become a directory
Running...
(6) Simply enter the TODO directory and hit the RUN button which will be
the very first button you see.
From here on out, simply follow (6) to run it.
Features:
* Unlimited number of lists - up to the memory of your machine
* Unlimited size for the lists - up to the memory of your machine
* Ability to scroll the lists by the line or page
* Ability to jump to the beginning or end of any list
* Ability to change lists via a catalog
* Ability to create new lists or delete old lists
* Ability to MARK and UNMARK items on the list
* Ability to UNMARK ALL items on the list
* Ability to delete any single item on the list
* Ability to delete ALL MARKED items on the list
* Ability to insert a new item anywhere in the list
* Ability to sort any list of information
GROCERY LIST
I have created a large (though somewhat incomplete) grocery lists, as a
default. It is large so it does take a bit of time to compile the GROB. Use
this list as an example list, and delete it if you need the memory or find it
unusable.
How To Use TODO
---------------
When the program begins to run, it will display six menu items assigned
to the menu keys. These six items are:
LIST - Catalog of all lists OR create a new list OR delete a list
ADD - Adds a new item to the end of the list OR inserts a blank item
EDIT - Edits the text of an existing item
SORT - Sort any particular list
MARK - Marks an item OR Unmarks an item OR Unmarks all marked items
EXIT - Exits the program and returns you to the HOME directory
The following lists the available KEYSTROKES from the main menu level:
UP ARROW - Scroll the current list towards the top - one item
ORANGE SHIFT UP ARROW - Move the current list toward the top - one page
BLUE SHIFT UP ARROW - Move the current list to the top
DOWN ARROW - Scroll the current list toward the bottom - one item
ORANGE SHIFT DOWN ARROW - Move the current list toward the bottom - one page
BLUE SHIFT DOWN ARROW - Move the current list to the bottom
DEL (keyboard key) - Deletes the current item
ORANGE SHIFT DEL (purge)- Deletes ALL marked items
LIST (menu key) - Get a catalog of all lists
BLUE SHIFT LIST - Enter the name for a brand new list
ADD (menu key) - Add an item to the end of the current list
BLUE SHIFT ADD - Insert a blank line ABOVE the current item
EDIT (menu key) - Edit the text of the current line
SORT - Sort the current list in alphabetical order
MARK (menu key) - Mark OR Unmark the current item
BLUE SHIFT MARK - Unmark ALL marked items
ORANGE SHIFT MARK - Same as MARK without the Startrek sound
EXIT - Stop the program and return to the HOME directory
BLUE SHIFT EXIT - Turn the calculate off (turning it on returns to
TODO automatically with no delay)
Here are some general comments about a couple of the commands...
CURRENT ITEM
The current item (eg., the item you are going to MARK, UNMARK, DELETE etc..)
is the one at the TOP OF THE DISPLAY. To move an item into the current item
area, simply scroll (UP/DOWN arrow) until it is the top item on the list. This
goes for catalog lists (LIST) as well.
LIST
When in LIST, all current lists in the current directory will be displayed, in
alphabetical order (eg., sorted). WHILE you are in this mode, UP and DOWN
arrow work (but PAGE UP and PAGE DOWN and GO TO TOP and GO TO END do not work).
The DEL keyboard key will DELETE a list completely from memory.
MARK
The MARK command allows you to place a marker next to items which you have
completed (eg., check 'em off). Hit MARK the first time to place the marker,
Hit MARK a second time (on the same item) to unmark. When you MARK or UNMARK
a 'startrek' type beep will occur to signify the mark. If you do not wish
to hear the sound, hit ORANGE SHIFT MARK instead. BLUE SHIFT MARK will UNMARK
ALL currently marked entries WITHOUT deleting them from the list.
DEL
The normal 48SX DEL key serves to DELETE the current item, when hit under
the normal menu (when hit while in LIST, it deletes entire lists). If you
hit ORANGE SHIFT DEL, the program will delete ALL marked entries - useful
for purging information you have already done.
STARTING UP
If you start the program, and the current list is not found by the program
(eg., you deleted it from the operating system level), the LIST command will
automatically be run by the program. If the LIST command does not see any
lists in memory, the BLUE SHIFT LIST command will automatically be run, allowing
you to create a new list.
OTHER KEYBOARD KEYS
If you hit an unknown key (eg., not known to the program), the program will
issue a very low tone. Try again!
Internals:
This posting is already too long to give you full details of the program.
Feel free to rip it apart and improve it - just post it back! One routine
you will probably want to add to your 'favorites' list is the routine named
R2D2. This, standalone, routine takes a single number from the stack and
makes your HP48SX sound like a device on Star Trek. The best values, for
the most convincing sound are the values 4 or 5. Simply type
5 R2D2
for a demo. The number indicates the length of time (eg., number of chirps)
for the speaker to make).
Another routine you will find useful is the SORT routine. To use SORT
independently of the program, simply place a LIST of STRINGS on Level 1 and
run SORT. This is NOT a bubble sort, but an insertion sort, and it only takes
as long to sort the data as it does to read the data one time (plus the linear
count to find the place to put the data).
Other items you will find useful, if reverse engineering the routines... The
variable 'DATA' contains the name of the current to-do list database. The
system creates TEMPORARY variables (only will be seen if you abort the program
while it is running). 'W' contains a number which signifies which item is
the current iten (1 - S). 'S' contains the total number of items in the list.
If you abort during a catalog, you will see CATTEMP which contains a list of
all you to-do lists. 'W', 'S' and 'CATTEMP' are all deleted and rebuilt
by the program.
Here is a brief listing of what the other routines do:
RUN - Runs the TODO program
SORT - Sorts a LIST of STRINGS in level 1
MON - High speed GROB editor, used to turn a Mark ON
MOFF - High speed GROB editor, used to turn a Mark OFF
INSTD - INSerts a blank item into the ToDo list above the current item
EDITD - EDIts the current item of the current ToDo list
NEWTD - Creates a NEW ToDo list
CATTD - Handles the LIST command catalog of lists
SEETD - Displays the current list (does NOT build it)
MAKTD - Makes the GROB associated with the current list
ADDTD - Adds a new item to the END of the current list
MARTD - Handles Marking and Unmarking of the current item
UNMTD - Unmarks ALL marked items in the list
WIPTD - Deletes ALL marked items in the list
DELTD - Deletes the current item in the list
R2D2 - Takes a repeat value from level 1 and issues StarTrek sounds
AGAIN... these routines should only be used for editing and changing the
program. Use the RUN routine to execute the program (just hit RUN) and the
program will automatically issues these routines for you in responce to the
menu keys you hit (as described above). I provided the details above only
for those who want to see how it runs!

In my previous note (announcing my 1.0 mods to the TODO program),
I mentioned a memory usage program I encountered while working on
TODO. I'd like to find out what solutions are available to this
problem.
The TODO program manipulates a large GROB which it creates with BLANK,
modifies one line at a time with REPL and then stores in PICT.
My problem is that the GROB may be larger than half of remaining
memory, and the above approach causes two copies to appear in
memory at once. I need a way to manipulate the PICT directly.
One solution I see is as follows:
Use PDIM to create the correct size PICT
Use a version of REPL (syseval?) which operates directly on the
PICT instead of on the stack
Another would be to somehow move the large GROB from the stack
to PICT rather than copying it (so that at any one time, only
one copy existed on the stack). From what I can tell, STO requires
twice the memory of the object being stored. This is either because
the store doesn't remove from the stack until the copy succeeds or
because the LAST STACK memory retained another copy of the stack
object. If this second guess is true, then I need a way to turn
off LAST STACK. I can turn off LASTARG, but haven't found out how
to turn off LAST STACK. A solution to this problem would make
TODO be able to operate on lists twice as large for any given amount
of free memory as it can now.
If any of the proposed solutions involve a SYSEVAL, do they work
for all versions for the 48?

If you have only 32kb > of RAM, it isn't worth bothering, you don't have enough memory to use > it. Actually, I think it will be possible to run in 32Kb with some careful space-savings. Here are 3 things which will help: 1) If someone answers my question regarding how to manipulate a PICT without having to have two copies of the PICT in memory, it should double the size of lists that can fit in any given amount of free memory. 2) Set the PW variable in the TODO directory to have a value of 131 instead of the 200 I shipped it with or 262 which I recommend. That will turn off horizontal scrolling and make the PICT only as wide as the screen. 3) Delete GROCERY.LIST or make it much smaller. It is still quite large even though I already truncated it once. If all the lists you're going to maintain are smaller than the GROCERY.LIST, then you should not be constrained to fit the large list in memory when you don't need it. 4) Use the smallest font ("-" key while displaying a list) as you'll be able to see more at once and the number of extra lines at the bottom of the GROB will use less space. Also, a couple other comments. Once I get #1 fixed, I will post the new version. My inclination is to post in clear text (and possibly ASC) so that machines with limited memory can download. There isn't much point in doing that now since the program is not that space-efficient yet and will be much better after #1. The TODO directory is about 6K and a list occupying 1 screen is about 2.3K (including blank space at the end of the list in the GROB). You should be able to manage with 32K, though fixing #1 should help a lot (because without #1, that same list would require 4.6K free to display). John
