This passes use strict and -w.

sub readPackage { my $filename = shift; open FILE, $filename || die "cannot open $filename\n"; local $/ = undef; my $file = <FILE>; close(FILE); $file ||= ''; while( $file =~ m/^[^\n]*(FUNCTION|PROCEDURE)(.*?)IS/msgi ) { my ($type, $declaration) = ($1, $2); print "$1 $2;\n\n"; } }

The other option is

my @procedures = ( $file =~ m/^[^\n]*(FUNCTION|PROCEDURE)(.*?)IS/msgi )

This will create an array of procedure type, declaration pairs, as a flat list. So grap them 2 at a time, and process.

The key to the regex is that using /s allows '.' to match across newlines, and /m allows the '^' to match the beginning of the line. I use the character class [^\n] to act like the '.' but without /s's special abilities.

This was based on reading the regex sections in the cookbook. This version does not handle comments. The one the I use at work is actually for 'use lib' lines and does handle comments.
