Returning Values

$a = "George"; $b = "Jetson";

$name = cat($a, $b); # $name = "George Jetson";

print "name = $name\n";

sub cat {

return "$_[0] $_[1]"; # return the two arguments

} # concatenated together

• A value (or list of values) can be returned by a subroutine

• To get these values, just assign your subroutine call to a variable
