Function Define/save Questions
Posted 23 May 2005 - 12:54 AM
What exactly does the ClassPad do when accepting Define fun(x)=... in main?
What exactly does the ClassPad do when saving a function?
In main I waited a minute or so and pressed clear/break.
I input right side of the above define in Program app and clicked save, ClassPad hanged - no "busy", no reaction, on/off does not work, nor does Clear and <-.
It returned to normal after umpteen minutes.
Any guesses as to what causes the hang? Solutions? Workarounds?
What is the preferred (safe, nice, you call it) way to get hanged ClassPad to work?
Batteries? Reset? Anything else?
P.S. I was forced to drop most of the activities, ClassPad included, for a quite long time.
Nice to be here at last.

also, have you upgraded to OS2.0 yet? i copy/pasted Define gamma(x)=lim(((n!*n^(x-1))/(PI(x+y,y,0,n-1))),n,oo) into the CP manager and it worked fine (though i assume you ment the pi symble and infinity).

Yeah, I thought so, that's why I asked whether there is any GENTLE way of restoring responsiveness

Yessir, OS 2.0 here. I didn't check whether it is fine or not after waiting for 10 minutes to save it.
BTW, in OS2(Warp?).0's Verify is really nice. I have not tested the speed of matrices yet, but lists seem to be a little bit faster and more stable.
I'm still waiting for non-10-base calculations and conversions (and probably Laplace, because that's one thing that can't be substituted or added(-in)), but I'm not holding my breath

i'll try it on my actuall CP as soon as i find some batteries >_<

By the way, Crimson, what happens with you? You lost your USB cable for the ClassPad, now I hear that its batteries are empty... You are not a very proud user!
Dear Lianna, the ClassPad behaves completely OK! You see, the Program Editor is compiled in very simple code, so it does not support even drag&drop, undo&redo...
The problem is that the busy icon does not work in the Program Editor. The ClassPad has to work for several minutes (as in Main module), but it looks like it hangs for some minute. You shall see exactly what I mean after a week or two, when you will download a BASIC program from me which is 35K large and you must wait for several minutes to re-compile it, save it, or even go to the breaking point. So, this is a normal behavour for the ClassPad. I know that it does not respond even to [Clear]/ , which would terminate almost any ongoing action.
The ClassPad Manager saves the files at a lightning speed and even can show a blinking cursor in a meanwhile, so that is why you did not notice the problem there.
Do not worry, since either your ClassPad will finish the ongoing operation (like it did in Program Editor), or it will display [Insufficient Memory]. Do not worry, this message can be displayed for two or three times at the most. See you soon! Bye!

if it has do look for an break point it has to walk from the beginning to this point, because it does not really know the address of the command. That's one reason because it's very slow.
