It's not just the allocation, but the access methods. Are you going to open
your socket with QSAM? VSAM? EXCP? The $$$$ Media Manager?

I don't think the list is much if at all different. Certainly there are
DYNALLOC *keys* that don't have a match in JCL, but those are mostly for
returning values. Are there different object types? I don't know.

There are some DYNALLOC keys missing for things that are inherently batch
JCLy; DD DDNAME= and of course DD * or DATA, and one or two others.
