no... it's the TI pic files that's missing the last row X_X
you'd have to have an Asm-lib that stores its pics as either prgms or Appvars

I can store everything but the 7-8 pixels in the VERY top right with xLIB

even if they seems to be gone they are still here, its just that the calc wont display them since this part is for the run indicator

It's not optomized, but it can be used in programs to solve problems as if it was the homescreen. (to some extent)

I made something like this a while ago. Here's an adaptation for quick use in a program by pressing mode.

That's your opinion. So please let us have our own opinion, too.
Thanx.

Something1990, that code can be optimized to:

Repeap A=E5 //When's this acctually going to be the answer?
input "",A
Disp A
End

Vladic, just because they can only afford an 83+ doesn't mean that a person should be excluded.

One interesting unknown fact is that finance variables run faster then even ans. I often use finance variables in phisics engines or other programs that need every slight speed boost they can get.

The finance APP (the one you can't delete) contains variables made specifically for that app that you can use in normal programming. You can always use them because you can't get rid of the finance app. They are faster because they are programmed differently than the other variables (which use built-in bcalls). These are processed by hooks (like xLIB) and executed from the APP instead of the OS's horrible methods.

Here's an interesting one:

If you want your programs and games to be smaller, don't use lowercase letters for the text unless it's really necessary. Lowercase letters and some other symbols are like Unicode on the calc and they take up two bytes for each one you use. If you have lots of text in your program, and you're using lowercase, try making it all uppercase and see how many bytes you save (doing this has saved saved up to 75% of space per program on my calc...)

This post is 588 bytes long. If you put this in your calc, it would be double that unless you made it uppercase.

dinhotheone · « **Reply #41 on:** December 09, 2006, 11:02:00 am »

Alot of the time i use
Output(X,Y,"I%"
Output(X,Y," ")

to output a % at X,Y+1 for loading screens because that is the only %sign on the calc (I% is a finance variable)

DJ Omnimaga · « **Reply #42 on:** December 09, 2006, 11:07:00 am »

thats an useful thing, i never understood why TI didnt made the % symbol avaliable in BASIC by default

Halifax · « **Reply #43 on:** December 09, 2006, 11:32:00 am »

yea same here I hated then and I never knew how to get a % sign without making it your self on the graphscreen but now I know so thanks

kalan_vod · « **Reply #44 on:** December 09, 2006, 01:05:00 pm »

You can use the percent that is to dots and a slash.
