Sorry, Bill, but if you code just the base name then all generations in the catlog will be conctenated - latest to oldest. Yes, COPIES is the number of copies to be put on the spool and does not apply to non-spool datasets.
Hari - you could could have found out the answer to the first question by experimenting and an answer to the second by referring to the manual (where you would also have found the answer to the first question).
The problem I have is that people can explain things quickly but I can only comprehend slowly. Regards Nic
Hari -- be aware that referring to all generations by using the GDG base name retrieves the data in reverse generation order. In other words, (0) will be the first generation you get, then the (-1) generation, then the (-2) generation. If this is not what you want, using GDG base name is not the way to go -- and you'll ned to reference the GDG generations by concatenating them in the desired sequence.
