You mean goto, next ??

Please name some of these languages ... or are you thinking of
perl5db.pl - the perl debugger | [reply] |

Python has 'pass', Bourne/Korn/Bash has ':', COBOL has (had?) NEXT-SENTENCE. But they were needed in those languages because (generally) of a lack of block delimiters, you shouldn't really need it in Perl. You can just have an empty block:
use strict;
use warnings;
my $x;
if (defined $x) {
# do nothing
}
else {
print "\$x is not defined\n"
}

If you still had in view perl debugger, you can use man perldebug, and find out there that you should use n or "next"
to step over fucntion. | [reply] |

Are you looking for Acme::Don't ?

Do you mean when you're in the debugger, and you want to step over a line that you know you don't want to run?
If that's the case, no.
