--- is there any inherent reason why future TOS versions can't be case sensitive, at least WRT file names (and directories)? i know that certain (perhaps old) compiler startup code forces upper case in several places (Fopen in GEMDOS may actually do this, or perhaps goofy GEMLIB/alcyon). i always found it strange that cpm, msdos, and tos could not deal with the difference between "a" and "A" in filenames, and have not been able to figure out a valid/necessary reason why the PC had taken a step backwards in this respect. i hope the answer isn't "tradition". and i hope the answer isn't that it would not fit in 192k... the next logical question (to atari) is, if no real reason, is this planned (at least with the TT)? -bill -- Bill Rosenkranz |UUCP: {uunet,texsun}!convex!c1yankee!rosenkra Convex Computer Corp. |ARPA: rosenkra%c1yankee@convex.com

I suspect that the tradition goes back to CP/M and the use of teletypes. But with CP/M it was easy to change -- there was a masking operation that converted lower case to upper case, and I just changed that to NOP (no-op) and had a full case sensitive cp/m. Interestingly enough, Microsoft BASIC could create lower-case file names which could not then be removed with CP/M commands! With TOS in rom the hack would be harder, but since it is possible to get all kinds of odd characters in file names by various errors, why can't a case-sensitive version of TOS be generated? -- William Silvert, Habitat Ecology Division, Bedford Inst. of Oceanography P.

Regarding case sensitivity of GEMDOS... At work I use both OS-9 and Unix. OS-9 is not case sensitive, although filenames will contain both upper and lower case in directory listings ("SOURCE" == "Source" == "source"). Unix, of course, is case sensitive. I prefer the OS-9 method (employee bias notwithstanding) because it allows me to use capitals where organization/convention calls for (directory names in caps, for example), but still makes it easy to specify filenames. Besides, I don't think it would be very good procedure to have both the file "stuff.txt" and "Stuff.txt" in the same directory. Perhaps there would be an easy patch to TOS to not have filenames converted to uppercase when written to the directory sector, but still have "open" calls use uppercase when comparing filenames for matches... -- ################################################################################ # Bill Sheppard -- bills@microware.com -- {uunet,sun}!mcrware!mwca!bill # # Microware Systems Corporation --- OS-9: Seven generations beyond __/_!! # #######Opinions expressed are my own, though you'd be wise to adopt them!#######

For one thing, most file selector boxes, and command shells, translate lower case characters into uppercase before processing input lines (sometimes they even echo back uppercase, but sometimes they don't, so you find this out the hard way). Neodesk and PCOMMAND and LGSELECT are three examples I can think of offhand. Another problem is that the people who write programs which have a call like fp=fopen("datafile.in","r"); assume that there is a file on the disk matching this name - but when we suddenlly add case sensitivity to TOS, what happens to the files which are on disk already? will they be considered all caps (so most programs can read them after this conversion to uppercase) or all lower case (so the c programs with lines like above will work)? It is a FACT that if such a convention were added, TONS of programs would need little changes to work again. I happen to use a few programs which are no longer being maintained by the author, and I don't have the sourcecode.

All you've said is "it's great - everyone who likes unix should love it!". Well, I love unix myself, I don't see the connection. Lets hear some support for your opinions.

PCOMMAND and NEODESK are not unix-like shells. the desktop does, however, force upper case, which is why it is a pain in the *ss to run unix utilites from the desktop, especially ones which have different meanings of "-c" and "-C". all this talk has nothing to do with TOS itself supporting (even toggling this feature on/off) mixed case file names. look, i'd like to have the option of switching case sensitivity on and off at will. i myself see no reason why this cannot be added. i myself like having important files in caps (like README and Makefile) since with a directory list, they appear set aside, and easy to spot (i.e. more productive). pls don't argue that YOU may find it revolting. I do not. and besides, if it is SWITCHABLE, then it does not impact you our any program in the slightest. i have discussed how this can be done in a previous note. all i want to do is find out CAN IT BE DONE and IS ATARI PLANNING ON DOING THIS? which apratt@atari answered. >fp=fopen("datafile.in","r"); i can't see how/why a program has to force case anyway, since TOS does it for you. it IS case insensitive, so DaTaFiLe.In is the same file as datafile.in is the same as DATAFILE.IN is the same as DataFile.In, etc. The only reason programs force upper case is for cosmetic reasons, i.e. for consistency. try it youself: #include <stdio.h> main() { FILE *fp; char buf[256]; fp=fopen("datafile.in","w"); fprintf(fp,"Hello\n"); fclose(fp); fp=fopen("DATAFILE.IN","r"); fscanf(fp,"%s",buf); printf("%s\n",buf); fclose(fp); exit(0); } i bet this will print "Hello". meaning it does not matter AT ALL what case the file name is. both fopens open the same file. i already mentioned that the program can make a call like this to force old, compatible behavior: Fcase(CASE_OFF); BEFORE doing anything, if it must. and i already mentioned that the desktop of TOS x.x which would have this new feature can have an additional menu item for configuration (which would cause Fcase be called if the menu state changes, just like the blitter). FOr those of you who still don't understand this, i offer this hypothetical desktop menu (for those who hate cmd shells): ________________________________________ | Configure | |---------------------| . . . . |---------------------| | X Case sensitivity | |---------------------| . ^ . . | .

I happen to use a few programs see above. it does NOT effect the programs, if implemented this way. and new programs can inquire the state of case sensitivity: state = Fcase (CASE_INQUIRE); or somesuch. here is the example program with this "new" TOS: #include <stdio.h> main() { FILE *fp; char buf[256]; if(Fcase(CASE_INQURE) == CASE_ON) Fcase(CASE_OFF); /* added...*/ fp=fopen("datafile.in","w"); fprintf(fp,"Hello\n"); fclose(fp); fp=fopen("DATAFILE.IN","r"); fscanf(fp,"%s",buf); printf("%s\n",buf); fclose(fp); exit(0); } for existing programs, the if(Fcase(CASE_INQURE) == CASE_ON) Fcase(CASE_OFF); /* added...*/ is done with the desktop menu selection, making it 10000000% compatible with older TOS. how can i make this any clearer? if the effort to do this is 2 manweeks (design, implement, debug, test, document), and it takes 50 bytes of ROM, WHY NOT DO IT????? sheesh! >which are no longer being maintained by the author, and I don't have the >sourcecode.

This depends on the TOS version. With TOS 1.0 I couldn't extract a file from a ZOO archive with the x option when I started ZOO.TTP from the desktop. TOS translated everything to uppercase and the X option is illegal with ZOO. I had to use the -extract option. After I replaced TOS 1.0 with TOS 1.4 I can use the x option. The X option still generates an error message. So TOS 1.4 is case sensitive, it only translates FILENAMES to uppercase.

TOS itself (or probably more properly GEMDOS), when dealing with filenames and file operations (notably GEMDOS Fopen/Fcreate/et al), remains case insensitive, forcing file names to upper case. my entire point is that there is no inherent reason to force upper case in GEMDOS, really. the actual bytes representing the file name written to FATs need not be upper case or lower case, but can be any ascii char. i believe it is GEMDOS which defines legal chars in file names. all i was asking for was a way to toggle GEMDOS into expanding this definition of legal chars as to differentiate between upper and lower case letters. and regarding breaking programs, i suspect that since if u pass Fopen a ptr to string "file.nam", on return, the string IS CHANGED (a definite "bug", IMHO, that i've always detested), forcing you to change your idea of the filename, programs have the modifications mentioned when parsing a filename AFTER an Fopen/Fcreate/etc and probably because of this flagrant disregard for sanctity of user data. such parsing may be done to isolate paths, extensions, etc, tho these examples look for non-letters (i.e. ".", ":", and "\"). drive letter seems like the only real reason to worry, or perhaps extensions. so rather than strcmp/strncmp, use stricmp/strincmp (ignore case). and yes, i know these are not in POSIX/ANSI C... -bill rosenkra@convex.com -- Bill Rosenkranz |UUCP: {uunet,texsun}!convex!c1yankee!rosenkra Convex Computer Corp. |ARPA: rosenkra%c1yankee@convex.com

You have a point, and I'll add to it. Case sensitive filenames are slower and more clumsy to type out. Only when you have filename completion in your shell ('a la gulam and unix csh), or a file selector written to show extra characters (read on) does this become moot. However, your next point I DON'T agree with. >And this is just a half-assed step towards a unix-like filesystem - if you >want a real unix filesystem, you gotta throw out all this TOS and MSDOS >bullshit and start FROM SCRATCH - we don't need all these tiny little steps >which make everything incompatible but look a little more like unix - give >me a break! There is a way, using some extra bytes (I forget how many, but enough to be useful) in the directory table which are presently "reserved" (by Atari) for each filename, that could be used to put a few more characters (or other attributes) into the filenames. True, a small step, but it could be made in such a way so that it would be upwardly compatible. It would be up to the disk driver (you'd have to write a new one) to decide how to use the extra information. You could use one or two of the bytes to provide an uppercase/lowercase bitmap for the other characters and the rest as extra filename characters, for example, just use all of them for extra filename characters, or other things (file protection bits, user id, etc...). If you wanted to go whole hog, you could use the extra bytes as a FAT pointer to an invisible, locked (but vanilla TOS) file containing lots more filename information. Or to a place on the disk mapped out so that old TOS treats it like as a bad sector... I argue that you could make it so that it wouldn't necessarily be incompatible with the present 8.3 case-insensitive filename system. You could use such a disk with a normal TOS file system, just that in a directory listing, you wouldn't see the extra attributes, and in a file-file copy, the extra bytes (probably) would not be copied. If any extra bytes are used for extra filename characters (e.g. 16.3 vs 8.3), the filename would be cut off at 8. But IMHO, you would be no worse off than before. About the only problem this is likely to cause is if you are trying to use two files that have the same first 8 characters (and the same 3 char extension) on the old TOS file system. The old TOS disk driver wouldn't be able to tell the difference between them. My guess is it will probably always choose the first of the two (unless you delete it) in the directory table for whatever operation you're doing. About all you'll need to see and use the nice new filenames from within your GEM programs is a new fileselector rewritten to accomodate the larger size of filenames (at least). Some shell programs not hardwired to the 8.3 convention, especially if they were originally ported from Unix, should work w/o modifications. Even the hardwired ones might only need a few trivial changes. There are other programs that do their own filename parsing, but in general these are not the "user-friendly" programs anyway. Atari itself might want to clear up just how "reserved" they presently consider the extra bytes in the directory table. My guess is that they won't be keen on the idea, since they've been going out of their way to go in the other direction (down towards DOS compatibility). plini b -- ----- Like ls * | grep string?

Well, some applications, upon finding the feature, might insist on using it, and not leaving it up to the user. Someone might write an application that creates internal data files named "foo" and "FoO" and requires them to be distinct. Realistically, this can probably be avoided, but the point is, it is not a given that people will be able turn the feature off just because it is made optional. Using the car example, if all there were in the world were ferrari's, then your boss could not expect you to drive through swamps. If the option to own a 4x4 became available, it is possible that your boss will be require you to drive through a swamp.

No. A well written application will test the tos version and bypass this. a poorly written application will not, but then these are not even guaranteed to run on any os other than what it was developed on (i.e. "undocumented" variables, locations, etc which apratt wisely warns us about). so why even bother keeping the guys who write lousy code in business by buying their products? i am sure DC/Beckmeyer/et al would not be around if they were not careful, and did not write good code. let the market decide. >Realistically, this can probably be avoided, but the point is, it is not a >given that people will be able turn the feature off just because it is made >optional. People WILL be able to turn it on/off. right from the desktop or with a 10 line (trivial) application. the system can be booted with feature disabled. the only thing i can think of which may break is if the state is saved to DESKTOP.INF and u try using the new version .inf on an older tos. this may be analogous to the blitter state. what happens in that case? will tos 1.0 die when reading a tos 1.2 .inf, if the blitter state is saved in the file? it sounds like u think that adding new features to an OS is bad, since new applications which use them will not run on older systems (unless they are well written - see above). so why even bother upgrading an OS? and u can get TOS upgrades (i.e. Rainbow TOS). infact, why even bother getting new equipment 20 years from now? today's software won't run on it in all likelihood. and what about things like MiNT, a really nice piece of work. MiNT applications will not run without MiNT (essentially an OS upgrade). the only difference here is that MiNT does not cost anything. a bona fide TOS upgrade may cost $100, if that. note that i realize that a disk saved with mixed case file names may be impossible to read on an older TOS. in that case, it should be up to the purveyor of the disk to decide how it should be written. if it is commercial s/w, then it is marketing decision. many, many programs do not run on 520s. that does not make them bad programs. it just means that for people to use them, they must have the correct hardware/OS. and people buy (or at least should, in most cases) computers because of the software they want to use. i REALLY don't want to talk about this anymore. i know it is 1) feasible, 2) won't really break anything (at least i have not heard any convincing arguments), so the point is now moot and really up to atari. -bill rosenkra@convex.com -- Bill Rosenkranz |UUCP: {uunet,texsun}!convex!c1yankee!rosenkra Convex Computer Corp. |ARPA: rosenkra%c1yankee@convex.com

I'd like to know in what way you find Atari's CacheXXX program absurd and non-functional? I recently switched to it after finding the cache built into my ICD booter to be less than optimal. I find Cachexxx to work much better and uses less memory other than cache buffer space. Of course reading the docs explains how to set up a variable data-fat buffer area for real fine tuning.

Exactly. The same goes for $399 programs for the Mac and MS-DOS machines. Even though you pay much more for them, they can't be guaranteed to work on future machines.

In addition, many programs convert all filenames to lowercase before presenting them to the user (especially command shells)(the Okami Shell leaves the decision whether or not to convert to lowercase to the user). In this case, "foo" and "foO" would turn into the same filename. But do you really plan to use filenames that differ only in their cases? New programs would certainly not rely on filenames being case indepentant in order to stay compatible. So they will certainly not trust in foo and foO being different files. Using files that differ only in their case would be discouraged on an OS with optional case insensitivity anyway because turning the feature off would suddenly make a lot of files have the same name. As for myself, I dont really miss case insensitive filenames, I'd rather see a Unix filename convention that doesnt force filenames to the filename.ext con- vention. How about the difficulty of implementing that? In the disk directory, the filename "foo.bar" is written "foo bar", and programs (like Fsfirst) replace the spaces by a singe dot. If the directory entry was "foo.bar.baz", it should be possible to recognize that this is not a standard TOS filename, so an OS extension should be able to handle filenames in both MSDOS and Unix convention. Back to the case insentivities, there is however one advantage given by filenames being not case sensitive: if you are using a command shell which has, say, an internal command named "test" (it will have if it resembles the Bourne Shell) (guess which Shell does?) and you have a program called test.prg, then typing "test" on the command line will invoke the internal command, so you have to run test.prg by typing c:/bin/test.prg or something if filenames are case sensitive, but if they are not, you can simply type "Test" to invoke the external command (which is I suppose a lot easier to type even for people who do not like to use the shift key.)

Well, EXCUSE ME Johnny boy! Fact is GUY, I just got a Mega STe, and CACHEnnn makes exactly ZIPPO performance difference in my hard drive. I hardly see that as Atari bashing, and I don't have any hard disk cache program for it, which I could really use. I didn't make ANY comment on HOW the software was written EXCEPT that for ME its USELESS on my machine. WHICH IT IS. What the hell does that have to do with me liking Atari or not? YOU IDIOT! --Gregory
