> Can you directly modify a string? If so please explain.

Yes.  Say you have a string, "Hi how are you, Jon?"
If you wanted it to say hi to Joe, you would do this:
:Sub(String,1,19)+"e"+Sub(String,20,1)->String

This takes 19 characters of String, starting at character
1, adds "e" to the end, and adds 1 character of String
starting at the 20th character to the end.  The result is
"Hi how are you Joe?".  Read about Sub( ) and Lngth
in the manual for more information.  The problem with
this is very slow, especially for strings longer than ~20.

It's possible but not easy.  I am not sure the best way to do
it, but I'm sure someone on this list knows a few tricks.
