Firstly i would like to thank you for ur replies and it was really a good thing to get the ideas and views of well experienced people.

        Most said Perl has built in fully dynamic data structures - arrays and hashes. These are in most cases sufficient for resident data needs. We have the extended featured functions for th ease in order to exploit the programming abilities....

FUNCTIONS: pop , push , splice , shift , unshift and many more and dont want to use etc.....

As jonadab said ...........

It's kinda like asking, "How do I implement an insertion sort in Perl?" or, to use a non-Perl example, "How do I tack in a speedboat?" Everyone's going to look at you funny and ask, "Why?"

But any wayz i felt it some thing like of learning a lot from all of you.
