matchchunk

[Ken Ray]

Richard,

You need to pass variables to hold the start/end chunk in the matchChunk
command (they don't need to have a value), but the regular expression needs
to have parentheses around the value you want to look for so it can
"extract" its location into the two variables. Like this:

on mouseUp
  local b,c
  put "abcdefg" & return & "hijk" into a
  put matchchunk(a, "(def)", b, c) into x
  put b && c && x
end mouseUp
