Hi all, LC 5.5.3. I made some tests with time stamps, where the first line beginning with a number was at about line 18,000: The classic cycle thru like Craig's and Bert's took +/- 8 msec Iterating by halves to +/- 28 msec Peters approach with matchchunk and lineIndex I didn't got to run (some execution error on lineIndex, I don't know)
So the good old pure repeat loop is still the best Thanks for ideas Tiemo > -----Ursprüngliche Nachricht----- > Von: use-livecode [mailto:use-livecode-boun...@lists.runrev.com] Im Auftrag > von dunb...@aol.com > Gesendet: Freitag, 1.
