TI-83 Plus programming (Basic?)

[-Demosthenes-]

Through experimentation (and some help from this site months ago) I can write programs from formulas to save time, and using the book I got a pixal to move around the screen using the arrows using the getkey function. I seem to have gotten as far as I can by myself.

 

1) Can you write a program that factors a trinomial (or other polonomials). I have no idea how this program could work. Or can you that can f.o.i.l. for you?

 

2) Games. The pixel that I could move around with the arrow keys didn't work very well. After a while I'd get the error message "memory." I ran out of memory to move around one pixel? How do games work so that they do not use up too much memory?

 

3) Are there any basics that I might be missing that would make it easier?

There are several things that can cause this problem. For example, if you're using a For() or While loop, you can't use a Goto statement to get out of it or you'll leak memory.

Chapter 16 of the manual, and http://www.ticalc.org is handy too.

Hey thanks, I'll be able to learn most of what I need to know from these
