You'll want to read up the "perlform" man page and see how to use multiple formats. There are several ways listed, but my favorite is shown below. (I got really bored and hacked on your program a little)

#!/usr/bin/perl -w

use strict;
use warnings;
use FileHandle;

my (%val, $total);
$total=0;

format DETAIL =
@<<<<<<<<<<<<<$@<<<<<<<<<$@<<<<<$@
$_, $val{$_}{"Price"}, $val{$_}{"Quantity"}, $val{$_}{"Price"} * $val{
+$_}{"Quant
ity"}
.

format SUMMARY=
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<$@
"-----"
Total value good in stock>>>>>>>$@
$total
.

print   "Packaged Goods Organizer\n"
.       "========================\n";

# Collect the data
ENTRY:
while (1) {

        BAR:
        while (1) {
                print "Barcode  :  ";
                $_=<>;
                chomp;
                last ENTRY if ($_ == "0");
                last BAR unless ($_ >= 10000000000) || ($_ < 100000000
+0) || /[^0
-9]/;
                print "Bad input (numbers only and between 1000000000 
+and 999999
9999)\n";
        }

        Price:
        while (1) {
                print "Price    :  ";
                $val{$_}{"Price"}=<>;
                chomp($val{$_}{"Price"});
                last Price unless ($val{$_}{"Price"}=~ /[^0-9\.]/);
                print "Numbers only\n";
        }
        Quant:
        while (1) {
                print "Quantity :  ";
                $val{$_}{"Quantity"}= <>;
                chomp($val{$_}{"Quantity"});
                last Quant unless ($val{$_}{"Quantity"}=~ /[^0-9]/);
                print "Numbers only\n";
        }
}

# Write the detail records
print   "\n\n\t\tGoods in Stock\n"
.       "\t\t==============\n"
.       "Barcode    Price   Quantity   Value\n"
.       "-----------------------------------\n";
format_name STDOUT "DETAIL";
foreach (sort keys %val) {
        write STDOUT;
        $total += $val{$_}{"Price"} * $val{$_}{"Quantity"};
}

# Write the summary
format_name STDOUT "SUMMARY";
write STDOUT;
close(STDOUT);

Specifically, I added the 'use FileHandle;' up front, renamed your formats to DETAIL and SUMMARY (and moved 'em closer to the front, where I normally put 'em in my programs). Finally, in the code, I put in the 'format_name' statements to tell STDOUT which format to use.

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
