use vars

In perlmodlib :

vars Predeclare global variable names (obsolete)

If this is obselete then what is the newer version of predeclare global
variables?

Basically I just want to include config file (variables which can be
changed by users, ie. path ) and it should available to all
programs/modules.

Any better way other than use vars?

myconfig:
---------
$input_dir = "/home/yourname/data";
$tmp_dir = "/home/yourname/tmp";
# etc...
return 1;

myprogram.pl
------------
#!/usr/bin/perl

use strict;
use warnings;

use vars qw( $input_dir $tmp_dir);

require "/etc/myprogram/myconfig";

# etc...
#

Replace things like

use vars qw($FOO)

with

our $FOO;

(unless you need to assure compatibility for versions before 5.6).
