Hi Jim,

The easiest way to do that without sacrificing the
speed advantage of repeat for each is to track the
index by means of a counter ; for example :
  put 0 into i
  repeat for each line tLine in tVariable
    add 1 to i
    -- do funny stuff, and use the index in i
    -- ...
  end repeat
  -- the other advantage is that i contains the number
of lines after the repeat

Hope this helped,

Jan Schenkel.
