I have a website with an auto complete function. So I've created a list of index words and want to use these as natural as possible. So choose a index word and put it into a variable, then hit the service with the first two chars of that variable, then the first three, the first four, first five.

Problem is I cannot find a function to perform some sort of substring function. Is this not available?

For now I will create 5 different lists (one for each length) and use the $LRand method.

In WAPT Pro you can use JavaScript to create substrings from index words. It's a better solution for your case.
