Packages

[scribouille]

Hi,
Well, my problem is the following :
-I have 2 packages A.pm and B.pm and one principal programm, main.pl
I try (but it doesn't work) to specify my 1rst packqge like that :
#A.pm :
package A;
require Exporter;
@ISA=qw(Exporter);
@EXPORT=qw(Sub1 %Var1);
@EXPORT_OK=qw($Var2);
%Var1=(1=>...,2=>...);
use strict #Is it the good place for it ?
my($Var2)
Sub1'={...}
1;
My questions :
How can I have a variable (for instance %Var) both :
->Visible and not writable NEITHER by main NORE by B
->Visible and midifiable by A (well, it could see easy but... not for me)
How I have to specify my package B and the good specification of A and the main
Thanks for your help

I don't think that's possible -at least I don't know how to do it. By placing %Var1 in @EXPORT, I believe that any module that does

use A;

has full(visible and writable) access to %Var1.

In fact, variables placed in either @EXPORT or @EXPORT_OK are fully modifiable by the "use"ing module. I could be wrong about this but this is my understanding.

Well, i tried different things but the only thing i found is declaring my different variables as global one and establishing that we can't touch this variable without being in the wanted package.
Thank's for your help
(but, if someone has an idea...)
