<P>Thanks to [blakem] and [mirod] my code looks like this.</P>
<CODE>
#!/usr/bin/perl
use strict;

use Time::Local;
my (@records, @report);
{

open my $fh, $data_file or die "Can't open $data_file: $!";
while (<$fh>) {
# skip blank and commented lines
next if /^\s*#/;
next if /^\s*$/;
chomp;
# We'll look for lines that describe a report:
if (/report:\s+sort\s+(\S*)/ ) {
@report = split /,/, $1;
} else {
push @records, [split /,/];
}
}
}
my %field = ( source => 0,
time => 1,

my (@sort_sub, @sort_description);
# Here is where we do the sub building
