Yup, that did the trick -- much obliged, runrig. Fixed code is: 
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
use File::Find;

my $dir = shift or die "bitte html suchen/ersetzen verzeichnis eingebe
+n\n";
opendir(DIR, $dir) or die "html suchen/ersetzen verzeichnis existiert 
+nicht: $dir";
closedir(DIR);

#works, but with warning:
#Variable "@myfiles" will not stay shared at fileFindTroubleshooting.p
+l line 34.
my @files = get_files($dir);

foreach (@files) {
    print "file: $_\n"

}

sub get_files {
    my $directory = shift;    
    opendir (DIR, $directory) or die "couldn't open directory: $direct
+ory";
    
    my @myfiles;
    my @directories_to_search = ("$directory");
    
    find( sub { 
            my $name = $File::Find::name;
            if ( $name =~ /html$/i && ! ( $name =~ /\.backup\.before/i
+ ) ) {
                $name =~ s|\\|/|; # substitute forward slash for back 
+slashes, icky but don't know a better way.
                #print "name: $name\n";
                push @myfiles, $name;
            } 
        }, @directories_to_search);

       return @myfiles;
}
