I really just threw it in for novelty... but it is fast. I like
SPLIT. I use it a lot in parsing and so on. Replace is fast too. I like the
REPLACE as well but I'd prob put it in a 1 to 5 FOR.. NEXT to get rid of
doubles spaces. The SPLIT/JOIN suffers the same prob.

But I think you're right ... The REPLACE is probably the simplest.

The loop through for ASCII codes is the best I think. In the one where I
passed a string I did an INSTR on the passed list for the ascii code of the
character. It meant I could pass an OPTIONAL string of ASCII codes like
"20,13,10".

I had a big problem  once with "smart" quotes, and that's what I used that
for.
