Why not just:

pawn Code:

stock SizedRandomUpperCharacters(size) {
    new str[128];
    for (new i = 0; i < size; i++) {
        format(str, sizeof(str), "%s%c", str, RandomEx(1, 26));
    }

    return str;
}

...and similar to other cases too.

This doesn't seem like a tutorial anyways, i don't see any usage examples (your test command isn't really an example tbh) either.
