Use the "x" operator (the repeat operator):
shlomif@telaviv1:~$ cat Test.pl
#!/usr/bin/perl
use strict;
use warnings;
print +('*' x 20), "\n";
shlomif@telaviv1:~$ perl Test.pl
********************
shlomif@telaviv1:~$
Note that "x" behaves differently if the left argument is parenthesised and if
it is not. The first is list repetition and the second is string repetition.
