snip

Short answer: yes, the vars pragma

The vars pragma has been depreciated for about a decade. Please use
the our keyword.

perldoc -f our


#!/usr/bin/perl -ws

use strict;
use vars qw($k);

print "$k\n"

Long answer: It is however a bad idea. -s does not do what you think
it does. It looks like what you want is the Getopt::Std module:

Please, enlighten us as to what -s does that believe the OP did not
believe it does.
-s is perfectly fine for rudimentary command-line switching, for short
simple programs that don't need the bulk of the Getopt::* modules.
