How do I create a program with GetCalc(? I can create appvars just fine, but trying to create a program crashes. (It really just freezes, actually.)
Don't you get the prgm token from the catalog, then type the name of the desired program?

Actually it's under the PRGM menu (PRGM I/O > D:prgm), but yeah, it's the same process as making an appvar. I noticed there are occasionally some issues when the program already exists, however, so try deleting the program before creating it again with GetCalc(.

Already tried that, providing that's what DelVar Str1 does :P

Are there any places in axe that goto will cause a memory leak. Does it cause any damage to use goto in a subroutine to go to another part of a subroutine, as long as it ends up returning.

I don't think that there are any memory leaks, so long as you make sure you never do anything like goto from a subroutine to your main code.

If you use 'goto' to jump to another subroutine, then as long as you return, there won't be any damage.  As a general rule of thumb, you have to match each 'sub(' with a 'Return'.

Can somebody else confirm?

I prefer to never use goto, only sub. I like to program in loops anyways. It keeps you safe from that issue (which is prevalent in many languages) as well.

Anyone ever consider the idea of axe libraries? Not axioms, which are more asm, but basically having a collection of programs that use sub() or similar to use the same easy, optimized code in all your progs. I like the idea myself, and it works in current Axe, you just tend to run out of symbols fairly often :P

Naturally. ;)
Hint: It is a utility to help a person program in axe ;)

aah. I was referring more to something akin to stdio.h in C, a lib, not a program.

Put your interrupt code in a label, then start it up with fnInt(LBL,SPEED) where SPEED is the frequency you want the interrupt to run at. It's all in the commands.html file :)

Treat the tiles as independent moving objects like with bullets and enemies (put them in an array) and redraw them every frame.

I'm trying to make an axiom and tried assembling memkit to make sure I had everything set up right. When I try to use it, axe just says bad axiom, how to I get axe to accept it?
