I am receiving the message "Use of Uninitialized Value" at certain points when running my script. I have check all the variables and they are all set to the correct values. The program is outputting the correct stuff, but I am trying to clean up the code. Any ideas on the easiest way to debug this code? Here is the function I wrote: 
sub gen_asp {
my(@cmd) = ();
    my(@cmd1) = ();
    my($rs) = ();
      my($rs2) = ();
    my($submit) = $sec_homepage;
    $i = 0;
    
    $submit =~ tr |\\|/|;
    
    my(@keys) = keys %temp_dcr_hash;
    
    foreach $key (@keys){


        if ("$temp_dcr_hash{$key}{LaunchDate2}" eq $today) {    
        
            $home{$key} = $temp_dcr_hash{$key};
           
         } # End of if statement 
        
    } # End of foreach loop



    if ("(keys %home)" ne "" ){

        foreach $key (@keys){

            if("$temp_dcr_hash{$key}{LaunchDate2}" lt $today)
              {

                       if ($key ne ""){
                        
                    $cmd[0] = "copy $workarea\\$sec_homepage\\data\\$k
+ey $archive\\$sec_homepage\\data\\$key";       
                            $cmd[1] = "del /Q $workarea\\$sec_homepage
+\\data\\$key";
                            $cmd[2] = "$cmd_path\\iwsubmit -w -u $vpat
+h/$submit/data/$key \"Content Expired.\"";
                        $cmd[3] = "$cmd_path\\iwsubmit -w -u $vpath_ar
+c/$submit/data/$key \"Submitted to Staging.\"";
                   } # End if statement

                      for ($j=0; $j<4; $j++) {
                       
                    print "$cmd[$j]\n";
                       $rs = `$cmd[$j]`;
                       print "$rs\n";
        
                   } # End for loop to run commands
    
              } # End if statement to check if the dcr is expired, arc
+hive any that are and delete them from the site        
    
         } # End foreach loop
        
         
    
        @home_sort = sort {$home{$b}{$modtime} <=> $home{$a}{$modtime}
+} (keys %home);

        
         $outfile = "$workarea\\Index.asp";
        $cmd1[0] = "$cmd_path\\iwpt_compile.ipl -pt $t_path\\home\\hom
+e\\presentation\\home.tpl -iw_pt-dcr $t_path\\home\\home\\data\\$home
+_sort[0] -ofile $outfile";
        $cmd1[1] = "$cmd_path\\iwsubmit -w -u $outfile \"ASP Created.\
+"";

          for ($j=0; $j<2; $j++) {
                       
            print "$cmd1[$j]\n";
               $rs2 = `$cmd1[$j]`;
               print "$rs\n";
        
        } # End for loop to run commands

        } # End if
} #end sub

The issue arises in the command calls at the end, after cmd1[0] is run the error appears (a few times actually) and then the program completes the commands in the loop. Thanks, Bill
