G'day PandiLakshmanan,

Firstly, please do not keep posting almost identical questions. You posted "Object in perl" a couple of hours before this one whose text was almost a copy of the title of this posting, i.e. "how to refer object to another object(a paragraph)". Both of these asked much the same thing. Both were very vague with respect to what information you're actually after. Both received responses asking for you to provide a clearer indication of what you're asking: the guidelines in "How do I post a question effectively?" should help you to achieve this.

On the basis of what you've asked so far, I suggest you read the following:

• perlmod: Perl Modules
• perlmodlib: Modules: Creation, Use, and Abuse
• perlootut - Object-Oriented Programming in Perl Tutorial

If those don't provide the answer you're looking for, you should now be in a position to ask a more informed question.

Also take a look at "How do I change/delete my post?" which will show you how to update a post rather than writing yet another new one.

We are trying to create a module in perl. I am unable to refer an object to another object. How do I refer?

Well, in perl, all objects are references, references point to variables (they reference variables), so if you've got two objects, they're two references ... read all about it in

Hello PandiLakshmanan and welcome to the monastery

If you post a short example code of what you are trying to do, the problem will be clearer for perlmonks to help with.
