Yes, using a disassembler.  but the code you'll see won't be in axe, but in assembly.
thanks, but i will trust you all :P (well anyway, it would take all the fun out of the game)

Also, do you want the hex code of an axe program? There are ways to do that pretty easily.

hex code? like i said, i'm a noob, i just got the idea XD
the hex code is the code of a program in hexidecimal numbers.

aaaaah, i really need to learn a bit or two (or more like 1000) :(

but that is still no clear answer to my question: is it possible to decompile and see the codes?

Depending on what "codes" you want to see. The compiled Axe program is in data form. You can easily convert it to ASCII hex using something like this "unsquisher", or you could disassemble it into assembly code with a disassembler. You can't get the Axe source back, though.

For example, say you have this program:

Code: (Axe) [Select]
:1+1

Once you compile it, it's in data form.

If you use an unsquisher, it gives you

Code: (Hex) [Select]
:AsmPrgm21010023

If you use a disassembler, it gives you

Code: (ASM) [Select]
LD HL,$0001
INC HL

But there's no way to get back to the Axe code.

I'm not an Axe programmer if that is what this is aimed at. However, in BASIC, you could do something like this:
Code: [Select]
Input "CODE:",Str1
ClrHome
If Str1="GARRMEOWRAWR
Then
prgmRAWRZ
Stop
End
If Str1="GIZZLEBOPS
Then
Asm(prgmPONG
Stop
End
If Str1="SOAGUYWALKSINTO...
Then
Output(1,1,"YEAH, I HAVE NOTHING
Stop
End
Output(1,1,"INVALID CODE!

well, sort of, but then no external progs or such, but just random things.
and since i would like to learn axe, it would be fun if it were my first prog (if it is possible, that is)

Ah, okay... Erm, I still need to learn axe too... And why doesn't axe just compile it to 210200? It would save memory/speed

Installing a parser hook may be a bit of a hard challenge for your first axe program, I would suggest starting smaller at something more like a moving sprite, a test game, or a tilemapper

I've disassembled and converted compiled Axe programs to apps before Axe got application creating support. ;)
But that requires a little bit of assembly knowledge, which I'll assume you don't have.
ticalc.org has plenty disassemblers - just pick one that fits your needs. ;)

well, i meant that others could decompile my prog and then see all the codes i put in...
if that is possible, it is a minus...

Nope, there are no Axe decompilers out there, so the farthest you can go would be to disassemble it into assembly. The Axe source is gone, in other words.

but that is still no clear answer to my question: is it possible to decompile and see the codes?

Ehh... assembly code, yes. But not very interesting (or fun) to read: http://omnimaga.pastebin.com/zCHk31V4

A homescreen hook would be much easier for this. But yeah, in any case a hook is pretty advanced. Try something simpler if you're just learning Axe.

well, sprites i can manage if they are 8x8 (i think). i wrote a BASIC converter so you can draw your sprite, and then it converts to hex code. works only for 8x8 though.

anyway, it is the idea, if someone else would like to do this project it would be most welcome. i can give ideas, and sprites and do little things with a bit of studying ;D

I also don't really get the "input" function. when i add the header, it changes "Input_" to "input" and now i can't really get it :(
maybe wrong topic, but i need for an example code (if possible).
