Hi, Neville. You may find a worthwhile improvement in speed if you avoid referring to the Unicode lines by their line numbers (as in "line k of fff").

Here's a way:

function findLineNumbersInUnicode pLinesToFind, tLinesToSearch -- returns a comma-delimited list of the line numbers of lines that contain any of the lines to find

  local tRegExp, tLineNumber, tLineNumbers

  repeat for each line tLineToFind in pLinesToFind

    put "(^[0-9-]*\t" & tLineToFind & ")" into tRegExp

    put 0 into tLineNumber

    repeat for each line tLine in tLinesToSearch

      add 1 to tLineNumber

      if matchChunk(tLine, tRegExp) then

        put tLineNumber & comma after tLineNumbers

      end if

    end repeat

  end repeat

  return char 1 to -2 of tLineNumbers

end findLineNumbersInUnicode



If you try the idea, please share your test results.
