Hi, All,

A colleague asks, "When did the requirement to pre-allocate the first
"goovoo" as a "seed" go away?"

TIA,

I don't think this was ever a requirement.
You needed to allocate a "PATTERN DSCB" with the
GDG base name (everything but the GnnnnV00).
This had to be on the same volume as the catalog the
GDG was in. This was used to get the default DCB info.
It could be avoided by specifying the DSCB keyword in
the DD card that created the GDS. There may have been
a time when you couldn't specify the DSCB keyword and
had to have a pattern DSCB, but I don't know.
