I agree that SAS says it cannot be done and would be interested to know if
someone had successfully done it. I believe Fabrizio is correct in his
assertion and the words "the very same time" are the important ones.  The ISPF
editor appears to allow multiple members to be opened at the same time. In
fact, it only opens the members to write to when you exit or issue a SAVE
command. To do these commands requires the directory of the PDS to be updated.
The directory for all intents and purposes requires an exclusive hold to do an
update, so at the "very same time" no two members can be written.

You can update multiple members as I recall using a separate view for each
member and then setting both views in the same datastep. But don't quote me on
that, I'm thinking back awhile.
