Thanks Everyone for your suggestions. It really helped. I shall freshen up from the documents suggested to me. But anyways, i would like to say, that unless any one works on any language, mastering it is difficult. When i go through the tutorials or documents, i seem to know. But practically, only when i work, i m getting to know more on the language.
And I really thank the whole group for helping each other in learning Perl.
