All I can see in the BEGIN section is print ARGV[1]. There's nothing wrong with that. Are you saying it does not work just with that? "#--loads of stuff" doesn't really help us if we can't see that "stuff". Can you be more specific about what you mean by "doesn't work"?

Pod::Simple::Debug(3pm) 				 Perl Programmers Reference Guide				   Pod::Simple::Debug(3pm)

NAME
Pod::Simple::Debug -- put Pod::Simple into trace/debug mode SYNOPSIS
use Pod::Simple::Debug(5); # or some integer Or: my $debuglevel; use Pod::Simple::Debug ($debuglevel, 0); ...some stuff that uses Pod::Simple to do stuff, but which you don't want debug output from... $debug_level = 4; ...some stuff that uses Pod::Simple to do stuff, but which you DO want debug output from... $debug_level = 0; DESCRIPTION
This is an internal module for controlling the debug level (a.k.a. trace level) of Pod::Simple. This is of interest only to Pod::Simple developers. CAVEATS
Note that you should load this module before loading Pod::Simple (or any Pod::Simple-based class). If you try loading Pod::Simple::Debug after &Pod::Simple::DEBUG is already defined, Pod::Simple::Debug will throw a fatal error to the effect that "it's s too late to call Pod::Simple::Debug". Note that the "use Pod::Simple::Debug ($x, somenum)" mode will make Pod::Simple (et al) run rather slower, since &Pod::Simple::DEBUG won't be a constant sub anymore, and so Pod::Simple (et al) won't compile with constant-folding. GUTS
Doing this: use Pod::Simple::Debug(5); # or some integer is basically equivalent to: BEGIN { sub Pod::Simple::DEBUG () {5} } # or some integer use Pod::Simple (); And this: use Pod::Simple::Debug ($debug_level,0); # or some integer is basically equivalent to this: my $debug_level; BEGIN { $debug_level = 0 } BEGIN { sub Pod::Simple::DEBUG () { $debug_level } use Pod::Simple (); SEE ALSO
Pod::Simple The article "Constants in Perl", in The Perl Journal issue 21. See <http://interglacial.com/tpj/21/> SUPPORT
