Hi Everyone, I'm fairly new to Perl through been using it for a while I never really go into the 'use Strict thing'. Now I’m writing me Perl code I want to start doing a better job of it.

Anyway when I use 'use strict' on the CGI below I get errors about the '$IMPUT' variable and that I should declare it. I’ve tried putting my in front of it when I pass the values in into it and even creating a empty version at the start of the script with ‘My $INPUT = “”;’ but I just can’t figure it out. I’m sure it’s real simple but I’ve spent a day looking for the answer with no luck. Thanks in advance guys.

#!c:/Perl/bin/Perl.exe -w
use strict;
use CGI;
print "Content-type: text/html\r\n\r\n";
# PDF 2 JPEG CGI
my $INPUT = ();
&DecodeInURL();
my $PDF2JPGEXE = 'C:\_TestSite\PDF2JPG\bin\pdf2jpeg.exe';

my $PDFFile = $INPUT{"file"};
print "**$PDFFile<br>";

my $output = 'Out_Temp\TempPDF%3.3d.jpg';
my $PDF2JPG_OutPut = system("$PDF2JPGEXE -w -d 90 -q 80 -s 240 300 -f 
+ $PDFFile $output");
print "<p>Output: $PDF2JPG_OutPut";




sub DecodeInURL {
    
    my $Decoded = $ENV{'QUERY_STRING'}; #Get Method
    $Decoded =~ s/%([\a-fA-F0-9][a-fA-F0-9])/pack('C', hex($1))/eg;
    print "$Decoded\n";
    my @INPUTVars = split /\&/ , $Decoded;
    foreach  my $pair (@INPUTVars) {
        if ($pair=~m/([^=]+)=(.*)/) {
            my $field = $1;
            my $Value = $2;
            $Value =~ s/\+/ /g;
            $INPUT{$field}=$Value;

            return $INPUT;
        }
    }
}
