Benchmark result averages over 10 runs on a 2700-line script:
filter lines of script 2612.6ms
filter script 2572.1ms
put "^local.*"&tLocal&".*" into tRegexString
put matchChunk(tScript, tRegexString, tStartPos, tEndPos) into tFound?
if tFound? then
put the number of lines in char 1 to tStartPos of tScript into tLine
filter tScript with regex tRegexString into tFoundScript
# alternate: no appreciable difference in timing
# filter tScript with "local*"&tLocal&"*" into tFoundScript
if tFoundScript is not empty then
put lineoffset(tFoundScript, tScript) into tLine
So matchChunk plus "the number of lines" is faster by ~150 milliseconds
over 2700 lines of text than filter plus lineOffset.
