Oh, alright. I thought my idea was pretty cool though~

Can you (or anyone) confirm if the next if... method works?

    Yes, you could do it like that:-

    my $linesToSkip = 2; while ( <FILE> ) { next if 0 < $linesToSkip --; # Do something here with the lines of interest. ... }

    I'd rather segregate the discarding of header lines (or whatever) from the processing of lines I'm interested in.

    my $linesToSkip = 2; my $discard = <FILE> for 1 .. $linesToSkip; while ( <FILE> ) { # Do something here with the lines of interest. ... }

    I hope this is of interest.

    Cheers,

    JohnGG
