Associative array explaination...

[rohitbasu77]

There are some predefine associative array, like

%ENV, %INC, %SIG...
@ARGV, @INC...

Can any one explain the use on @ISA and @EXPORT, @EXPORT_OK, %EXPORT_TAGS.

You can find out more by reading perltoot which will be a much better explanation than mine.

perlvar also should have some explanation about perls predefined variables

perldoc: perlvar

Let me put a example now:

Pak1.pm contains:
[CODE=perl]package pak1;
use strict;

@EXPORT = qw (&sub1 &sub2 &sub3); ---- 3 function will be exported

my $x;

sub sub1{
.....
......
}

sub sub2{
.....
......
}

sub sub3{
.....
......
}

1;[/CODE]

pak2.pm contains:
[CODE=perl]package pak2;
use Exporter;
use pak1;
@ISA = qw (Exporter pak1) ------if some function is not found pak2 then it goes
------ to search Exporter and pak1 module.
--------inheritance property
$x = 5;
sub sub4{
.....
......
}
1;[/CODE]

[CODE=perl]#!/usr/bin/perl

use pak2;
use strict;

print " \n the value of x is: $x";[/CODE]
