Hi all, this could be trivial, and I suspect the answer is that the regexp engine is smart enough, but suppose I want to test the following:
$extention =~ / \.bat | \.BAT /x; is the following a better solution? $extension = lc $extension; $extension =~ / \.bat /x; In other words, when testing for all-lower or all-upper cases should I first trasnform to one of them or use a regexp with alternatives? Any suggestion? Thanks, Luca -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
