Well, there are more goodies coming down the pipeline... in the "WIP" build, I now have FOR/NEXT and GOSUB/RETURN support:
FOR <var> = <start> TO <end> [STEP <stepval>]
<var> is the name of the var to track the value (Incremented on NEXT)
<start> is the value assigned to the named variable the first time through.
<end> is the value <var> is compared against on "next" - if it's greater, ActionScript continues AFTER the NEXT
<stepval> is an optional increment (or decrement, if <start> is greater than <end>) on each NEXT
BREAK skips to the appropriate NEXT and exits the loop prematurely.
So that's FOR/NEXT operation in a nutshell. It should clean up code nicely...
Pretty straightforward... put subroutines in your script, stay "local" with variables and such. On "RETURN" the script will return to the line AFTER the GOSUB.
There you go. I might do DO/WHILE if I get around to it....

Quick q: Is recursion supported?
Dec 17 2003, 02:42 AM
Bravo... I don't know how you do it man... but anyway you slice it up, You have nudged XBMP out of my number 1 spot for favorite app and that was not easy to do, trust me... I am definitely going to have to pay your tipcup a visit when I get some change... keep up the good work

Heh. I asked whether nested FOR loops are supported in the other thread, but here I asked for recursion
Like recursive factorial computation
* Ignore all the syntax errors
SETVAR N 5
SETVAR result 1
MUL result %N%
SUB %N% 1
IF# N==1 GOTO Blah

Bad things. Now I see how exploits work. So you could have people writing exploits for MXM if it didn't prevent stack overflows
. But I don't know what use the exploits will be.
But good to see a responsible programmer taking care of this

As for the if blocks, they can be easily converted to a whole slew of GOTO statements. I wrote a little prog to do this, but right now it has problems recognizing code blocks (inside ifs) more than a line long.
Update: Fixed that bug, click to download MXM Scripter pre-alpha 1.1

umm im kinda a newb at this xbox stuff ... and i would like to know what this "For/next And Gosub/return" is about

It's all for scripting.
Sort of like BASIC programming.
You can do stuff like write/read xml files through scripting, copy/delete/renames files and folders, display stuff on the screen. Basically a limited programming language for the xbox that is easy to learn, that runs inside MXM.
In other words, don't worry about it, as you can use MXM without knowing any of this.
