I figured the filter command would carry at least some overhead for

I wrote the test below to compare it with walking through a list line
by line, and the results were surprising:
on mouseUp
put fwdbCurTableData() into s -- gets 10,800 lines of
-- tab-delimited data
--
-- Method 1: filter command
--
put format("*a*\t*r*\tr\t*\t*\t*\t*\t*") into tFilter
put s into result1
Richard, I'm too busy (lazy??) to create some data and test this for
timings right now, but this filter is more complex than you need - it
verifies that there are the right number of tabs. You could simplify it to
put format("*a*\t*r*\tr\t*") into tFilter
and should get the same results more quickly.
