The 48SX says to lock lower case do alpha <-| alpha, and then when you lock the alpha keyboard, you will get lower case. This works fine, except that when I lock alpha again, I'm back to upper case. How do I get it to always be lower case whenever I lock alpha? Also, to go back to an old question, how do I free up ALL unused memory. I KNOW that MEM does garbage collection, and I KNOW that LASTARG, LASTSTACK, and LASTCMD use some memory, but I am referring to memory used by the graphics applications, and I believe PICT in particular. For example, if I do an ON-C, and turn off the 3 LAST.. commands memntioned above, MEM shows I have 9099.5 bytes free. Now if I run a program that uses the PICT (I have one that displays the earth rotating on its axis) and terminate its execution, and now I do a MEM, I show 8011.5 bytes free, over 1K less. =================== Late Breaking News Flash!! ========================= Bob Martin, in a fit of stupidity, suddenly discovers "PICT PURGE", and how, after its execution, all memory is again free to be accessed!! ========================================================================== Sure enough, after I do a PICT PURGE, MEM shows 9099.5 bytes free again (of course, after I also purge PPAR). So all is well on question #2. However, if anybody has an answer for question #1, please let me know.

Partial answer to Bob Martin's Question #1: "How do I get lower-case lock to ALWAYS be on?" I don't think you can. If you press [alpha] [lshift] [alpha] from the command line, do your stuff, then press [ENTER], you have to press [alpha] [lshift] [alpha] again the next time. HOWEVER: If you're editing an object in the CL or the EW, the 48 saves your "lower-case lock" for you as you toggle in and out of alpha mode. In other words, Start creating an object (say a list or program) in the CL, or an algebraic in the EW (well, some of still like it...) Press [alpha] [lshift] [alpha] to get "lower-case lock". Do some alpha stuff, then press [alpha] to exit alpha mode. Press [alpha again, to get back into alpha mode. You should still be in lower case. CONCLUSION: It looks like "lower-case lock" will be preserved as long as you don't exit to the stack display. Regards Ray Depew IC's by Bill and Dave rrd@hpfitst1.hp.com

Bob, I believe what you want to do is alpha alpha <-| alpha. The first two to lock in alpha mode, and the shift alpha to lock in lower case. )>/----------------------------------------------------------------\<( )> Michael VanLoon--Iowa State University of Science and Technology <( )> Bitnet: "TNCU2@ISUVAX" Internet: "TNCU2@CCVAX.IASTATE.EDU" <( )> Hewlett-Packard, Macintosh, and Jazz forever! <( )>------------------------------------------------------------------<( )> "My hair has a mind of it's own.

It is indeed possible to always get to lower case alpha characters. You just have to be in USER mode, and then define a command sequence to tell the HP48 that you have pressed alpha-shift-alpha. I think this can be done by using the SYSEVALs posted recently. I have antoher problem. I can only get the programs from the HP BBS into a file containing all the other communications text at well. AND it is quite difficult to get a nice macintosh file from this garbage. So I woulld be glad if somebody swould mail me GROBer and the HP48 fonts for the Macintosh. thanks, Povl -- ******************************************************* Povl H.

No. It still only locks lower case for the current alpha "session", not permanently. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bob Martin | ram@tellabs.com ...!uunet!tellab5!ram Tellabs, Inc. |"Listen to me now, and believe me later" - Hans & Franz Lisle, IL. 60532 |"Flibble-dee Floo" - Grumpy Old Man

It locks lower case for the current command line, not for the current alpha session. As proof, note that you can use alpha <-| alpha to lock lower case WITHOUT locking alpha. You can then press some non-alpha keys, and later in the same command line press alpha <something>, and <something> will come out lower case. The lower case lock and the alpha lock can each be toggled independently of the other, and each stays in effect for the current command line or until it is explicitly turned off. -- Dave Seaman ags@seaman.cc.purdue.edu

Yes, but now if I hit enter, do some other things, and then do alpha <something>, <something> will be UPPER case. You can only lock lower case for the NEXT time you select alpha. After that is completed, the next alpha after that will be upper case. Some ways around this are a USR key which assigns alpha <- alpha to some key, or using vectored enter to accomplish it, so it is possible to permanently lock lower case, but only in a slightly (more or less) roundabout way. Anyway, the whole reason why I was going to be using lower case all the time has disappeared, so it really isn't too important to me any more. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bob Martin | ram@tellabs.com ...!uunet!tellab5!ram Tellabs, Inc. |"Listen to me now, and believe me later" - Hans & Franz Lisle, IL. 60532 |"Flibble-dee Floo" - Grumpy Old Man

Where I said "command line" above, I should really say "command line or edit session". However, the essential point is that it works as long as you don't press ENTER. That is precisely why I phrased it the way I did.

Locking lower case does not work only for the NEXT time you select alpha (as you just said again), but for EVERY time you select alpha within the current command line or editing session, unless you specifically cancel the lower case lock. That was my point. Try it. -- Dave Seaman ags@seaman.cc.purdue.edu

This is the second time I've seen someone mention a USR key. How do I do this? I've read and reread the small section on the USER mode in vol 1 and can't figure out how to create such a key. What key do we assign since we need one the three modifier keys? (Ie, what column and row do we use?) And how do we make the 48 think that someone has hit this key? Does someone have some code for a very confused 48 owner? >=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- >Bob Martin | ram@tellabs.com ...!uunet!tellab5!ram >Tellabs, Inc. |"Listen to me now, and believe me later" - Hans & Franz >Lisle, IL. 60532 |"Flibble-dee Floo" - Grumpy Old Man George
