Communication is very important in IT, and so far you are doing an excellent job of showing why you do not belong in IT. "mainfarme" is not a word in the English language. "mainframe" is, however -- so either your topic subject is mis-spelled or you do not know enough English to be able to identify proper words or not. Neither bodes well for the future of your IT career. Furthermore, assuming you had a typo, using a subject line of "mainframe" on a mainframe forum provides absolutely no information about your question -- again no communication is occurring. Definitely NOT a good sign for your future in IT. Neither of your questions can be answered as posed since you provided almost no information to help us -- again, a communication failure on your part. You should read
