( #3333=superdoc: print w/replies, xml ) Need Help??

Coming as I do from an OO background, I would approach the problem like this:

#! perl use strict; use warnings; { package FunctionsFactory; my $class = ($^O =~ /Win/) ? 'WinFunctions' : 'LinuxFunctions'; sub new { return $class->new(); } } { package WinFunctions; sub new { return bless {}, shift; } sub f { print "Windows f()\n"; } sub g { print "Windows g()\n"; } } { package LinuxFunctions; sub new { return bless {}, shift; } sub f { print "Linux f()\n"; } sub g { print "Linux g()\n"; } } my $funcs = FunctionsFactory->new(); $funcs->f(); $funcs->g();

Output (on my system!):

19:49 >perl Windows f() Windows g() 19:53 >

This scheme allows you to keep all the code in one file, and gives a clean/transparent interface to the functions concerned.

Hope that helps,
