I have dont know what is going wrong with my code, but when i print it via my TI 84 Plus, the solution shows for 0,00000001 second and then disappears... How can i make it last on my screen?


Code:
startTmr
ClrHome
Disp "AX+BX+C=0
Prompt A,B,C
B-4AC→D
PlotsOff :FnOff :ClrDraw:AxesOff:ZStandard

You ClrDraw at the end, which erases everything on the screen. Simply remove the ClrDraw on the 2nd to last line.
You may want to consider optimizing your code. I see a lot of redundant statements, and using the graphscreen seems like a bit of a drag. I suggest going through each line and asking "what does this do?"
That will help you identify what is not needed, and maybe familiarize you a bit more with the different commands.
Well-stated, Mr. Womp Womp. Welcome to Cemetech, svafa, and good luck with your program. Where you have "P" before your "ClrDraw", did you mean to add "Pause "? Is this something you created yourself, or copied/modified from elsewhere? I have some resources I might suggest to help you learn TI-BASIC more rigorously, but other people here might clamor about self-promotion. Wink

Fixed.

But seriously, KermMartian teaches compsci at NYU, so his book is legit.
