Thanks for all those comments. I have done it but i dont know how i have written the code somehow like this: The hash used here is just the declaration, it is defined dynamically. 
use strict;
use vars qw(%line $time);
use mod1 qw(%line);
use mod2 qw(%line $time);

[download]
in the main .pl file and in the .pm files it is like this 
use strict;
use Exporter();
use vars qw(%line);

[download]
in the mod1.pm, and 
use strict;
use Exporter();
use vars qw(%line $time);

[download]
in mod2.pm. Can any one explaing why and how is it working without giving any warnings.
