I did something like this:

It shows a field and parses through the field, highlighting each character
in blue as it considers it, and marking CR in red.

It has two buttons, one which simulates repeat for each line, another which
simulates repeat with i = 1 to the number of lines. It then does something
with each line.

It logs the actual thing it is doing at each step along the way, so you can
see the difference in steps taken, and gives an overall time for each
