Replacing Characters

[JB]

Instead of my goofy repeat command
your replace can be modified to some
thing like the code below.

command replace_maybe @rString
      repeat with i = 58 to length( rString ) step 58
      put return after char i of rString
      end repeat
end replace_maybe


But the problem is similar to what my repeat was
doing and that is the first line has one extra char
and the last line has more chars than other lines.
