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.
