Ok...after spending an hour on my battle engine for my current project, I have a lot of questions that I hope I can get some help with. Thanks in advance

1. Files: Does having a file open cause any significant issues? It seems to me that if you can't call subroutines with file open...and that they make the program rather glitchy in general. Is there a way to "close" files?

2. Lowercase letters: Let's say you want to create a database for the different items in a game. So let's say you wanted the first few bytes to be the name of the item, then how much it raises your HP by, and then how much it costs in the store. Example Data(^TN,^TE,^TT,^TH,^TA,^TM, 9000^r, 9000^r, ^TT,^TI,^T-,^T8,^T4,^T+, 42^r, 1337^r)->GDB1 So then to display the name of your item if the item # is in variable I, you'd write
For(A,0,5)
Text(A*5,0,{I*12+A+GDB1}>Char
End


But now let's say that you want to use lowercase letters, which are two-byte tokens. I tried this:
Data(^TN^r,^Te^r,^Tt^r,^Th^r,^Ta^r,^Tm^r, 9000^r, 9000^r, ^TT^r,^Ti^r,^T-^r,^T8^r,^T4^r,^T+^r, 42^r, 1337^r)->GDB1 ...
For(A,0,5)
Text(A*5,0,{I*18+(A*2)+GDB1}^r>Char
End


..except it didn't work. Any ideas?

edit: looking at the documentation again and thinking about the >Tok command. That might be it

and 3. This whole data and code limit thing. So let me know if this is right, because I'm really confused:

Nostub: only up to 8192 bytes of executable code. Data isn't code, but since Axe mixes subroutines and code, it's possible that your >9000 byte program with 2kb of data won't work.
Shell: only up to 8811 bytes of executable code. Data isn't code, but since Axe mixes subroutines and code, it's possible that your >9000 byte program with 2kb of data won't work.
App: only up to 8811 bytes of executable code. As much data as you can fit into the app is OK

Oh, apps can have >8811 bytes of executable code? awesome

Ok...thanks quigibo. A few more q's now lol:

4: In BASIC, putting Goto's inside If:Then blocks causes memory leaks. Does it do the same in Axe? (resolved)

5: How does Pt-Mask( work? (i figured it out )

6: Do apps take up any user RAM while being run?

7: Is there a way to retrieve the amount of free RAM and display/store it somewhere as a two-byte number? (resolved)

Thanks

In response to 7: It's Asm(EFE542).

So you can display it with
:Disp Asm(EFE542)►Dec
or store it with
:Asm(EFE542)→A

EDIT: It's a b_call that finds the amount of free RAM.

I think this might have been said in another topic, but for (7), you can simply do:
{E9828}^r - {E9824}^r->VARto get the amount of free ram.

In response to 7: It's Asm(EFE542).

So you can display it with

Code: (Axe) [Select]

:Disp Asm(EFE542)►Dec
or store it with

Code: (Axe) [Select]

:Asm(EFE542)→A

EDIT: It's a b_call that finds the amount of free RAM.

Wow I didn't knew we could store Asm() stuff to a variable/pointer. If you are going with a pure-Axe way to do it, you would have to use Mighty Moose's way, though.

In response to 6, no apps don't take up space in RAM.  But the side effect to this is that you can't use self modifying code with your program data, you would have to copy it to free ram to make modifications.

Bcalls are ALWAYS slower, but they're much smaller, so it depends on what kind of trade-off you need with size vs speed.  For something like getting the free memory, I'm guessing you wouldn't be calling it 1000 times a second so the bcall is probably fine.  Conversely, division for example has a smaller bcall, but I don't use it because the performance is much more important for a function like that.

Sorry, that was a typo -_-
