    wordfrequency => "...",
);

## debugging WordFrequency
exit WordFrequency( \"this is in memory test file with test words", "t
+est" );

my $file = Prompt( $messages{welcome}.$messages{promptfile} );
my $word = Prompt( $messages{promptword} );

WordFrequency( $file, $word );
exit;
sub WordFrequency {
    my( $file , $word ) = @_;
    open my($fh), '<', $file or die $messages{byenofile};
    my $freq = 0;
    ...;
    if( $freq ){
        print $messages{wordfrequency}, $freq, "\n";
    } else {
        print $messages{byenoword};
    }
    return $freq;
