in thread subroutine syntax

For that matter, let's take a look at uses of the return function. (perldoc -f return)

my $xyz = 15; my $var = &example($xyz); print &example($xyz); sub example { my $tmp = shift || 0; my $tmp += 49; return $tmp }
Now, you can set the global $var to by equal to the return value of the subroutine. Also, you can just print the return of the subroutine if you like. return is a very handy tool when it comes to subroutine programming and cleaning up perl code.
