Sorry I wasn't so clear. Let me go into a little more detail on what I’m trying to accomplish. The @list is coming from a file handler that returns a list from a sys. command. The length varies is so I’m just cycling through it in while statement. In a nut shell all I’m doing is looking to see if all the elements are present in the new "@list" and let the user know which elements are missing. 
open($syscmd,"ps -a |") || die "unable to open system command $!\n";

$count =0;
while (<$syscmd>){
    
@list1 = split(" ", $_);
    @list[$count] = @list1[3]; 
    $count = $count + 1;
}

$set = 0;

foreach $val(sort keys(%prolist)){      #checks through every element 
+in the hash one by one.
        while(<@list>){ #looks through each element in list for a matc
+h
            if ($prolist{$val} eq $_ ){ #if the match is found 
                 $set = 1; #sets this to true so that the below if sta
+tment isn't executed
                last; }
            }
        
    if ($set == 0){ #prints only if there is no match            print
+ "NF: $prolist{$val}\n";
    }
    
    $set = 0; #resets boolen
}
