I'm having trouble changing the reference of a subroutine.   Here is how I start. 
$localfile  = 'customer';
$ulocalfile = ucfirst($localfile);
$newdir  = "$path/$localfile";
MakeDir();
#
#  SECOND GET THE FILE LAYOUT AND INITIALIZE FILE MANAGEMENT TOOLS
#
$getfile      = "Read$ulocalfile";
$updatefile   = $guestfile = "Write$ulocalfile";
$deletefile   = "Delete$ulocalfile";
require "$path/files/$ulocalfile";
require "$path/processes/GuestBook";

In just a little bit I set $updatefile = 'ProcessGuestBook';

The main script calls the subroutine by &$updatefile. So far so good. Now when I get into the ProcessGuestBook subroutine I have a need to change &$updatefile to refer to it's orginal value. I thought I could just reset it by $updatefile = $guestfile and then invoke the subroutine &$updatefile. What I get is an error letting me know that the script can't find the subroutine.

Any way to change the reference on the fly?
