So in other words,
Code: [Select]
If Q=0??Blarg
stuff
End

This doesn't seem to work properly. it only displays weird signs and all.
Code: [Select]

Thanks in advance. :)

You need to do text(0,0,x>Dec

Yep, use >Dec. Otherwise it treats X as the pointer to a string, and the data at $000A probably isn't one :D

Thanks, it helped. :D

EDIT:I have another question.
I want to save the value of x to a string, so I can see it out of my program. The following doesn't seem to work.
Code: [Select]
:10->x
:x->str1

You would have to write code to manually extract the digits, convert to tokens, and put into a TI-OS string variable.

Maybe something like this (input is in X, uses 5 bytes at L1 to temporarily store characters):
Code: [Select]
L1+5→A
0→B
While 1
  B+1→B
  X^10+'0'→{A-1→A}
EndIf X/10→X
Copy(A,GetCalc("Str1",B),B)

A bunch of questions here:
1) How would I compare strings? (The equivalent of the C/C++
strcmp
) Doing
If Str1=Str2
doesn't work (and it won't compile).
2) How do I check if a program exists without using MemKit?
3) How do I check if an application exists?
4) How would I do arrays (and arrays of arrays) in Axe?

i am rather sure that will only check one byte equivalence.

As it happens, Axe has a command just for that purpose!
expr(Str1,Str2)

I believe you mean Equ▶String(STR1,STR2).  expr (exch) just exchanges two chunks of data and would need a third argurment telling it how much to exchange. ;)

Whoops, silly me and my spatial thinking; the two are right next to eachother in the catalogue and I looked at the wrong one in my head when I answered. Silly me!

To answer number 4:

There really aren't 'arrays' in Axe, but there are large chunks of memory that are kept more-or-less empty, which is the next best thing :P

'L1' is a pointer to a chunk of memory about 714 bytes long.

To assign the numbers '3', '6', '20', in the zeroth, first, and second positions, do...

Code: [Select]
3->{0+L1}
6->{1+L1}
20->{2+L1}

Here's a convenient trick to simulate an array in an array -- but only if each array inside the array is constant.

Code: [Select]
NUMBER -> {array_index * subarray_length + subarray_index + L1}

(the subarray_length starts with 1, not 0)


This is actually identical to how you do tilemaps:

Code: [Select]
{row * row_length + column + POINTER}

or...

{Y * width + X + POINTER}

If each subarray has a different length, you could perhaps make an array containing pointers to each array, although it feels a bit inception-esque to me.

My website: Currently boring.

Projects:
Axe Interpreter
   > Core: Done
   > Memory: Need write code to add constants.
   > Graphics: Rewritten.  Needs to integrate sprites with constants.
   > IO: GetKey done.  Need to add mostly homescreen IO stuff.
Croquette:
   > Stomping bugs
   > Internet version: On hold until I can make my website less boring/broken.

Yup. This is how compressed and variable-length maps are dealt with.

Hope you don't mind the ad, but I have a full tutorial on arrays in Axe right here on Omnimaga.

The final topic? Arrays of (pointers to) arrays ;)
