Hello Guys,
I have a weird problem that I couldn't understand,Below is my code,When I query a particular index of a string using string this is working but when I tried this inside a foreach loop It is not working with a variable(pawn i.e iteration number )

Could someone please explain me what Im doing wrong.

string files = 'abcdefgh';
//s@fileN = files[0] //this is working 

int pawnList[];
if (s@pieceName == "pawn"){
    pawnList = expandpointgroup(0, "*");
    foreach (int pawn ; pawnList){
       //s@g = files[0]     // this is working
       s@g = files[pawn]; // this is not working
       //@P = detail(1, sprintf("%s%i",(x[@g],2)));
    }
}

Thanks a lot in advance!

Are you running in detail mode?

This simple test worked for me.
string chars = "abcdef";

for(int i=0; i<@numpt; i++) {
    setpointattrib(0,"char",i,chars[i],"set");
}

I have a feeling it could be the globbing pattern in expandpointgroup causing the problem, don't think it likes “*”. Try taking the asterisk out
expandpointgroup(0, "")

not sure what is the expected result here

- if pawnlist has more members than your files string, you'll obviously get “” as in the last iteration you are trying to get element out of range and since you are doing 
s@g = files[pawn];
only the last element counts as it's overwriting all previous, that's why 
s@g = files[0];
seems to work as you will always overwrite with first index character “a”
- if pawnList has less elements than files string, then you will see the the character at the index of the last element
- since you are using s@pieceName and s@g, I'm assuming you are running per point
that means that every point with s@pieceName==“pawn”, will have the same s@g as all of them would get the same list and unnecessarily iterate over it until they reach last element and use that index to try to get your character, doesn't seem useful

Im very sorry that I couldnt reply earlier.

Thank you so much guys I got it working.
Like Thomas said
only the last element counts as it's overwriting all previous, that's why
this is the mistake I did and
I got it working using setpointattrib function as Enivob has did
to change the point number on each iteration.

Also this suggestion from friedasparagus helps to make this work!

Thanks a lot for all of you guys.
