[Kaliber]

As the function says...it sets the value of an argument..for example:

PHP Code:

stock setter(...)
{
    setarg(0,0,999);
}
//Usage:
new x=0;
setter(x);
//and now x=999 


The usage:

PHP Code:

setarg(arg, index=0, value) 


First the argument...in this case 0...cause we only pass 1 argument, and we know its always on the first place so 0.
The index of integer Values is always 0 (only for strings to go through an arrays it can be 0-sizeof(arr))
And last the value you wanna set
