Calling a Subroutine

• Use &subname;

&printFooter;
• This assumes no values are passed, but you can pass values.
• Put those parameters in parenthesis following the subroutine name.

&printFooter("Brandan Jones");
• Once in the subroutine, you can access each parameter with the special underscore array.  Just like any other array, but its name is _

sub printFooter {
    # print the author line
    print "<br>Authored by: $_[0]\n";
    print "<br>jonesbl@one.net\n";
    print "<br><a href = \"http://oz.uc.edu/~jonesbr\">http://oz.uc.edu/~jonesbr</a>";
}
