It is still possible to build commands like: V (xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx),OFFLINE The start command is not needed, and should be eliminated. If there are any developers left working on that product that know what they are doing they will agree, at least once they know the facts. Unfortunately, I don't know who is left working on that stuff, or even where the development is done, since I left in 2001.

I think the use of one character procs goes back to Punch cards. Too many holes - too little action... However, the main question I have is - Is it still necessary to do this? According to EMC they indicated that the reason they added the S DEALLOC was because varies were taking upto 6 mins. So the use of S DEALLOC was to speed that process up. However, in todays processors and Storage Arrays, is z/OS really that slow at issuing a V xxx,OFFLINE and the kicker (S DEALLOC) is required? And the EMC software does a one on one vary. I am not sure, unless a total rewrite is done, that they could bunch the commands up if that were possible. In our case, we do not have our snap volumes sequential - always one here and one there, so a massive vary offline command could not be created.
