AW: to find the first numeric line?

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
