Hey I'm a new for using axe parser, so i don't know alot of tricks and syntex. But I have programed a fair amount to understand basic commands. Anyway the problem I am programing a side scroller and the way I want to program someone walking is by testing getkey in a main repeat loop. And if a getkey equals a certain number like 2, then I want to change what it outputs by changed the value of the string 1. So In the beginning I set string1 to a value, (the character facing to the right), and when someone hits the left arrow key I want the person to turn to the left. So I want change the value of string1 to and image of the person facing to the left. But apparently you can't do that because every time I try to compile the program I get ERR: duplicate. So is there any trick to doing this or am I going in the complete wrong direction? Any help is greatly appreciated! Thanks

In case you couldn't understand what I was trying to say, here is the code:

:.BLA<br />:<br />:ClrDraw<br />:<br />:[4E4E447C440C1222]→Str1<br />:<br />:0→A<br />:56→B<br />:Repeat getKey(15)<br />:If getKey(1) and (B≠56<br />:B+1→B:End<br />:If getKey(2) and (A≠0<br />:A-1→A:End<br />:If getKey(3) and (A≠87<br />:[3A3A121E12182422]→Str1<br />:A+1→A:End<br />:If getKey(4) and (B≠0<br />:B-2→B:End<br />:If B<56<br />:B+1→B:End<br />:ClrDraw<br />:Pt-On(A,B,Str1)<br />:DispGraph<br />:End<br />Generated by <a href="http://sc.cemetech.net">SourceCoder</a>, © 2005-2011 <a href="http://www.cemetech.net">Cemetech</a>

I'm not quite sure what you mean by that.  Can you type out your source code either by hand or with Source Coder so we can see exactly what you're doing, so we can help you?

I think he's trying to store a value to Str1 and then store another value to it later in the program.

In fact, it gets even worse: They're just placeholders. When The compiler does its second pass, what it's doing is going back through the program and putting in the location of all the different pieces of data you're using, which are added at the end of the program after the last C9 [ret], so that the program ends execution before it reaches a bunch of bytes that are not intended to be executed. This is not entirely accurate, however, as Axe apparently mixes code with data sometimes, and I'm not quite sure how that data doesn't get accidentally executed.
Read the documentation (it helps! Really!), keeping in mind that whenever "program memory" is mentioned, what is meant is that those bytes get added to the compiled program as-is, placed in a location code execution will never reach.

This is not entirely accurate, however, as Axe apparently mixes code with data sometimes, and I'm not quite sure how that data doesn't get accidentally executed.

The only time code will mix with data is when Axe adds its own sub-routines, like with the DispGraph command.  Basically, then any data defined before the first DispGraph is placed before the DispGraph sub-routine in the code, and any data defined after the first DispGraph is after it.

Is this supposed to happen, or is it a big?

No, the data-mixing thing

.BLA

ClrDraw

[4E4E447C440C1222]→Pic1

0→A
56→B
Repeat getKey(15)

If getKey(1) and (B≠56)
B+1→B
End

If getKey(2) and (A≠0)
A-1→A
End

If getKey(3) and (A≠87)
[3A3A121E12182422]→Pic1
A+1→A
End

If getKey(4) and (B≠0)
B-2→B
End

If B<56
B+1→B
End

Pt-On(A,B,Pic1)
DispGraphClrDraw

End
I think this is fairly better, but haven't tested it yet.

It didn't work it gave me the same answer

DUPLICATE? Oh yeah sorry, here's a fixed code:

.BLA

ClrDraw

[4E4E447C440C1222]→Pic1

0→A
56→B
Repeat getKey(15)
Pic1→O

If getKey(1) and (B≠56)
B+1→B
End

If getKey(2) and (A≠0)
A-1→A
End

If getKey(3) and (A≠87)
[3A3A121E12182422]→O
A+1→A
End

If getKey(4) and (B≠0)
B-2→B
End

If B<56
B+1→B
End

Pt-On(A,B,O)
DispGraphClrDraw

End

Another solution:
You take a DirectionVariable (let's use D).
You put your 2 sprites at the beginning.
The first one is pointed at Str1+0, The second one is pointed at Str1+8.
Then you guess what's next.
I made a spelling mistake in the word Right but it is on purpose.
If it doesn't work, blame me and give me a -1.
Of course, you have to replace "[FacingLeftSpriteInHex]" by the hex code of your FacingLeftSprite.

:.BLA
:ClrDraw
:[FacingLeftSpriteInHex]→Str1
:[FacingRiteSpriteInHex]
:0→D
:0→A
:56→B
:Repeat getKey(15)
:If getKey(1) and (B≠56
:B+1→B:End
:If getKey(2) and (A≠0
:0→D
:A-1→A:End
:If getKey(3) and (A≠87
:8→D
:A+1→A:End
:If getKey(4) and (B≠0
:B-2→B:End
:If B<56
:B+1→B:End
:ClrDraw
:Pt-On(A,B,Str1+D)
:DispGraph
:End
