Dear JohnGG

Thank you very much for your prompt reply! I really appreciate it! I did run into some small problems because my computer did not recognize the code(had many errors). After some research I found out that this is because I using windows (I feel even more beginner now for not figuring that out), but as a result I had some difficulties understanding the code because I am used to a completely different way of writing code(some lines are still difficult for me to understand, but I get what you're doing)

Could you maybe check whether this 'translation' is correct, because when I replace the first line by using strict and warnings it provides me with 2 errors later in the code

$ perl -Mstrict -Mwarnings -E ;

    my $wordsFH = "woord.txt";
    open(INPUT, $wordsFH) or die "Cannot open $filename";
my %words =
   map {chomp; $_ => 0 }
   <INPUT>;

my $rxWords = do {
   local $" = q{ | };
   qr{(?x) \b ( @{ [ keys %words ] } ) \b };
   };
print "Regex is $rxWords";

    my $textFH = "4.txt";
open (texting, $textFH) or die;

my $text = do {
   local $/;
   <texting>;
   };

$words{$1} ++ while $text =~ m{$rxWords}g;


print "$_ => $words{ $_ }}" for sort keys %words;

Furhtermore, I still have 2 problems that I need to tackle and of which I am not sure how to handle them. 1 Is it possible to extract the total number of 'hits'? $total ++ while $text =~ m{$rxWords}g; works, but may I incorporate it so that I do not have to use the regex twice. 2 Is there a simple addition to calculate the total number of words? (is setting up an array with chop the easiest solution?)

Again, thank you so much for your time!
