I don't want to delete it, For my knowledge purpose I needed to know why that ISPF is not getting deleted.
? Then why do you keep saying that you cannot delete it? And why would you want to delete ISPF? I think you mean soemthing else. ISPF is a software product - it is all the panels you use and a lot of the progrtams behind them.
regards does not have an apostrophe. An apostrophe indicates a letter, or letters, missed out as in don't = do not, or ownership e.g. Dave's book.
Do not worry too much about this last - I may be doing similar to a moderator on another forum who keeps using 'loose' instead of 'lose'!
The problem I have is that people can explain things quickly but I can only comprehend slowly.
