Looks good, and Zaxo covered the rest of the points. I just want to point out the my $vlnum = 0; is sort of ugly there: you never use that zero. If I do not explicitly want a specific initial value for a variable, I purposely leave it undefined so that I get a warning if I use it before I was planning to. In this case you can roll the initialization and input together: chomp (my $vlnum = <STDIN>);

my returns a valid Lvalue, that is, you can write my $var just about anywhere you can write $var.

Beware though: my ($vlnum) = <STDIN> (note the parens) is not what you want here. It gives you list context, in which the <FH> operator slurps the entire input first, then you get the first line assigned to $vlnum, and the rest is thrown away.

Makeshifts last the longest.
