You can open a filehandle to the system's /dev/null and then select
that filehandle to make it the default.  Make sure you reselect the
original filehandle when the subroutine is done.  For example:
$ perl -le'
print "Start";
open my $devnull, ">", "/dev/null" or die $!;
my $old_fh = select $devnull;
mysub();
select $old_fh;
print "End";
sub mysub {
   print "In mysub";
}
'
Output:
Start
End

P.S.  Please don't use a word processor to compose a post to a
technical list/newsgroup.  Or at the very least, turn off the word
processor's auto-capitalization feature.  You make it impossible for
anyone to copy and paste your code...
