I really want this to be possible:

Code: [Select]

"Up"->Str1
"Down"->Str1
I'd love to see that

"ERR:DUPLICATE"
And help doing something would help be useful...
Also, this was already mentioned I believe, but I second whoever asked for the size of the program* to be displayed on the "Compiling..." screen.
*like it does for apps, maybe?

"help working would help"...wow

You can always use a variable as a pointer to a string, and change that variable. For example, P is used as a pointer in the following program:
Repeat getKey->K
End

If K=4
("Up")->P
ElseIf K=1
("Down")->P
Else
("Neither")->P
End

Disp P
("String") tells Axe to insert the string data at the end of the program and return a pointer to it. The parentheses are important because it tells Axe that it is an expression and needs to return the pointer, instead of it being a simple data definition (in which case no code is generated)

If you are going to use a string more than once, it is a good idea to give it a name, though. If you inline the string each time, the data will be added again and again. (Well, unless Quigibo made it check for duplicates, but I think that would be a waste of processing time)

This is what disassembly is for

;getKey stuff here
ld hl,($8700) ;$8700 = K
ld a,l ;K=4 check
sub 4
or h
ld hl,$01
jr z,$+3
dec l
ld a,h ;Standard If statement code
or l
jp z,EndIf
ld hl,string ;If statement contents
ld ($870A),hl ;$870A = P
EndIf:
;Other stuff


string:
.db "Up", 0

Thanks, didn't know that. I don't understand how the parentheses work, though...

Well, try "Up"->P. Axe will give an error, because when a line starts with a double quote Axe is expecting it to be stored to a static pointer (like Str1A), or else just inserted at the end. Starting with parentheses tells Axe that you are actually evaluating an expression here, and thanks to the inline data support Quigibo added recently, a pointer is returned to the inserted string.
