That's what I was thinking. I just didn't know if it would automatically 
get garbage collected. I keep writing that way then. :)

Yes, as I said, it is doing what it claims. I just didn't know if there 
was a way to make it use the string only, instead of the string and the 
characters. Someway of making that string appear as single unit.

It works great on my playlist for the first 50 tokens.
Genesis 1-50. Gives me exactly what I want.

When it hits 'Exodus' the 'E' causes problems and its downhill from there.

ft _ fc substrings.

Does similarly to your code. It gives me array with 13875 substrings.
I'm shooting for a collection with 1189 items.

Thanks for the information.

I keep trying.
