Replacing Characters

[JB]

Another thing to consider is the characters are
not in any specific crder.  It could be cfacded or
anything else.

If is use a repeat for each char and the variable
as a counter that resets every three times then
I only need to make one pass through to make
the changes.  But there might be a faster way.
