The excessive number of dollar signs in all things DEC-related does
get one in trouble with Perl.  You have a double quoted string which
will do variable interpolation, so '$9' and '$dka0...' are
interpreted as variables.  You want to either escape the dollar signs
or put the filename into single quotes.  These may illustrate how
that works:

$ perl
print "$1$dua99";
 ^Z
$ perl
print "\$1\$dua99";
 ^Z
$1$dua99
$ perl
print '$1$dua99';
 ^Z
$1$dua99
