in reply to Need a better way to count input lines

You could do:

# while (not eof FILE) { ... } # or... until (eof FILE) { my (@lines) = map scalar <FILE>, 1 .. 3; # work with $lines[0], $lines[1], $lines[2] }
You need the scalar there, because you only want to get one line at a time.

    I've never used map before. It looks like @lines ends up with three elements because of the "1 .. 3" range. .oO(Verrry useful)
    Would the loop work the same if you used until (eof FILE) instead of the while?

    Update: Thanks for the update!
