Dear Monks,

I have searched high and low and cannot find the
answer to this problem I am having.

To demonstrate here's my code:

#!/usr/bin/perl -w

use strict;

my @names;
my @items;

sub processRec {
        my $fh = shift; #ref to filehandle
        while(<$fh>) {
                chomp;
                s/\cM//;
                last if /^$/;
                last if /^\d-RECORD$/;
                push ( @names, /ITEMNAME-(.*)/);
                push ( @items, /ITEM \d-(.*)/);
        }
}

open( FH, "<data");
while(<FH>) {
        if ( /\d-RECORD/ ) { processRec(*FH); }
}
close(FH);
for my $name ( @names ) { print "name = [$name]\n"; }
for my $item ( @items ) { print "item = [$item]\n"; }

This works fine most of the time.
But here is a case where it doesn't work ...
$ cat data
1-RECORD
ITEMNAME-bob
ITEM 1-socks
ITEM 2-shoes

2-RECORD
ITEMNAME-bill
ITEM 1-hat
ITEM 2-hair piece
3-RECORD
ITEMNAME-mary
ITEM 1-roach clip

4-RECORD
ITEMNAME-jimmy
ITEM 1-peanuts
ITEM 2-tooth pick

Here's the output from that case
name = bob
name = bill
name = jimmy
item = socks
item = shoes
item = hat
item = hair piece
item = peanuts
item = tooth pick

What happened to mary?


If there was a new line after the line ...
ITEM 2-hair piece
... I wouldn't have a problem.

I suspect that I need to do something like this ...
sub processRec {
...
   if (/^\d-RECORD$/) {
      put_line_back ($_);
      last;
   };
...
}
