(Though I'm sure a few monks can come up with an unpack solution or a module that handles fixed-width fields)

Wow...I wish I could do that. :P

I would so use it, but my teacher would get suspicious. Thanks a lot. :)

unpack is better with fixed-width records

my ( $name, @tests ) = unpack( 'A20 A3 A3 A3 A3', $line );

With 5.8.0+, you can even do

my ( $name, @tests ) = unpack( 'A20 (A3)4', $line );
[download]

or

my ( $name, @tests ) = unpack( 'A20 (A3)*', $line );

Update: Heh, I hadn't noticed the bit about unpack at the bottom before posting.

Confucious says "you must did not try everything then" :)

So very true...
