Is it possible to change @EXPORT during runtime? I'm trying to import subroutines in the following manner: - I have a file called DBLib.pm which imports a file "DefaultLib.pm" via a "use". DBLib.pm ############### package DBLib.pm use strict ; require Exporter ; use DefaultLib ; use vars qw(@ISA @EXPORT @EXPORT_OK); @ISA = qw(Exporter) ; - DefaultLib.pm explicitly sets @EXPORT = to a list of functions I want to export into DBLib.pm DefaultLib.pm ############### package DefaultLib ; use strict ; require Exporter ; use vars qw(@ISA @EXPORT); @ISA = qw(Exporter) ; @EXPORT = qw(&default_code) ; - SybaseLib.pm, OracleLib.pm are set up the same way that DefaultLib.pm is set up. The overall question is that I want to be able to write a separate perl script that makes a call to "use DBLib ;". The DBLib.pm file will have a section of code to test for an environment variable of DBTYPE and determine which additional library to "use" (SybaseLib.pm, OracleLib.pm, etc)... When the database specific library gets imported (SybaseLib.pm) any subroutine with the same name as a subroutine in DefaultLib.pm should get redefined and use the one in SybaseLib.pm. Additionally, to reference any subroutine regardles of which pm file it actually exists in should be able to be called from an outside script by use DBLib ; # default code here would be (same for all db's) &DBLib::default_code ; # db specific code here (main script doesn't know which db its connected through) &DBLib::add_user ; This I hope can be accomplished by using the AUTOLOAD subroutine to check for the existence of the subroutine being called and decide where to branch to using the following sequence. -look first in DBLib:: -next look in SybaseLib:: # (or whatever DBTYPE was set to) -last look in DefaultLib:: -error and exit if the subroutine hasn't been found The part that doesn't seem to work is that the functions from SybaseLib.pm don't overlay any subroutines with the same name in DefaultLib. So to simplify my question, is what I'm trying to do possible? I have tried many different approaches to accomplish this so, I have much of the code written allready. This is all very stripped down in hopes that it would make more sense without too much detail at first. Hope someone out there can help. Thanks, Jeff
