New Split String function returns nada

Hi,

I used the alternate splitstring function, but now the script returns nothing.

Code:
function SplitString(str       ,i ,j ,char ,slen ) {
    slen = length(str);
    for (i=1; i<=slen; i++)
        char = substr(str, i, 1);
        if (char ~ /[0-9a-zA-A]/)
            string_array[j++] = char;
    string_array[0] = j;
    return slen
}

Any idea?

Sorry, the alternate version of the function SplitString was written too quickly and untested.
A new version (tested) :
Code:
function SplitString(str       ,i ,j ,char ,slen ) {
    slen = length(str);
    for (i=1; i<=slen; i++) {
        char = substr(str, i, 1);
        if (char ~ /[0-9a-zA-Z]/)
            string_array[++j] = char;
    }
    string_array[0] = j;
    return j
}

Jean-Pierre.
