I can answer one part of this. GDGs can be members of PDS or PDSE. This has been true for a long time. The actual generated member name is different than for a GDG dataset. Lloyd

If I want to reference or browse a PDSE 2 member generation other than the latest, is it possible to do so? Am I just missing the doc somewhere? 2. Is this not an error or at least an illogical statement in the JCL reference? Under DSNAME - Cataloged data set name it says dsname(member) Specifies the name of the permanent partitioned data set (PDS) or the partitioned data set extended (PDSE), and the name of a member within that data set. If the member does not exist and DISP=OLD or DISP=SHR is specified, the allocation will succeed, but the job will fail when the data set is opened for input. If the member does not exist and the data set is opened for output, the system will add the member to the data set. member 1 to 8 alphanumeric or national characters, or a character X'C0'. The first character must be alphabetic, national, +, or -. If the first character is + or -, the member is a part of a generation data group. dsname(generation) Specifies the name of a generation data group (GDG) and the generation number (zero or a signed integer) of a generation data set within the GDG. That member description is not right, is it? If the first character is numeric, + or -, it's not a reference to a member of a PDS or PDSE at all -- it specifies a generation data set, right? Or is this support for member generations and I am not reading it correctly? Also, member syntax has nothing to do with whether the dataset is cataloged, right? The syntax is exactly the same with a VOLSER reference or for a temporary dataset, right?
