Use of uninitialized value within %dict in concatenation (.) orstring at

Hi,

Sorry to open a new thread,

Use of uninitialized value within %dict in concatenation (.) or string
at ./translate.pl line 21, <$fh> line 128.

Here is the whole code (based on the guide form all of you):

#!/usr/bin/perl

use warnings;
use strict;

my $file = "dm_proAB.xpm";

open my $fh, "<", $file or die "could not open $file: $!\n";

my %dict;

while ( my $xpm_file = <$fh> ){

	if ($xpm_file =~ m/([A-Za-z]).+"([0-9.]+)/) {
		$dict{$1} = $2;
	}
	
	elsif ( $xpm_file =~ /^"(\S+)[",]$/) {
		$xpm_file =~ s/(.)/$dict{$1} /g;
		print $xpm_file;
	}
}

here is a brief part of the "dm_proAB.xpm"
(The full version I uploaded to:

"W  c #6F6F6F " /* "0.846" */,

"c  c #484848 " /* "1.08" */,
"d  c #414141 " /* "1.12" */,
"abcdbacd",

The output is:


Use of uninitialized value within %dict in concatenation (.) or string

1.5 1.5 1.35 1.31 1.35 1.35 1.5 1.5 1.5

I don't understand the message well even I can do a basic guess,

Thanks,
