in reply to reading two files in parallel

Something like this?

while (1) { my $a = <F1> or last; my $b = <F2> or last; # use $a and $b here }

    This is a nice way to do it, however I would alaways advice against using $a and $b as variable names as they are "magic" names for sorts and bugs where your variables are then shadowed in a sort can be hard to track down, so better avoid potentially troublesome names.
