Hi David,

In this case, wouldn't it be easier to keep track of
the linenumber you're checking, instead of using
lineoffset to go through the entire text every time?

on mouseup
  get  the selectedtext of me
  put char 1 to 3 of word 5 of it into tcat
  put 0 into j
  repeat for each line i in me
    add 1 to j
    if i contains tcat then select line j of me
  end repeat
end mouseup

Back to lineOffset now: if some lines are very much
alike one another, you may want to
  set the wholeMatches to true
before using lineOffset, to make sure you have the
correct line.

Hope this helped,

Jan Schenkel.
