Title: copy command not working with expression as size
Post by: Michael Pang on March 03, 2015, 04:17:56 pm

why does this corrupt my ti84s ram?

Code: [Select]

1->A
Copy(L3,X+2,A)while this works

Code: [Select]

Copy(L3,X+2,1)
much thanks! Btw I have 1.1.2

What's the other code around it?

I'm trying to make a file compression program which will be useless but fun :)
I have an integer B, A bytes in L3 and N bytes in Y that I need to store to a new appvar.

Code: [Select]

GetCalc(L2,A+N+2)->X
B->{X}[sup]r[/sup]
and then the previous code.

What's at L2? You know you could just, like, GetCalc("appvMYAPPV",A+N+2)
What is the result of X? As in, is it Non-Zero?

L2 contains the string for the new appv. It's copied and modified from the OS's str1.
X is 42000 something

the lists in axe point to different areas of the calcs memory. maybe this is the reason why it crashes your calc.

So your code is this?

Code: [Select]

1->A
1->N
GetCalc(L2,A+N+2)->X
B->{X}r
Copy(L3,X+2,A)

Well, like I said the entire program works fine if I change the size parameter to a constant. So I suspect something is wrong with the parser. For example, the app variable doesn't copy properly if I delete it and then create it shortly afterward with getcalc, but if I move the delvar earlier in the program it works. Without the DelVar, it doesn't copy at all - just overwrites with 0's. I think this might have something to do with memory latency if it's non-blocking, or just a corrupt copy of axe.

there's other stuff before and after, but yes. I've commented out and recompiled wihtout copy command and it works as expected. I've even tried replacing copy with a for loop and everything works (just a bigger file size)

Version is 1.1.2. I probably should have tried updating before all this :p

Glad I could help! Hoping in seeing some topic for a great game/utility/program soon, hehe :P

I do actually have a lot of random programs that I've made over the past two years in high school. Started out with math programs in ti-basic, then I found axe and started making games and stuff. Too bad I never really finished making a full game with menus and levels and all, since I'd always just write the core engine and then move on to something else :)

If anyone's interested, I could upload axe source for checkers, connect 4, or reversi (most of the code is AI). I also have a neat birds-eye POV second- person shooter.
