Enhance LISTDSI to display number of generations for PDSE V2 with member generations

LISTDSI should be enhanced to display the number of member generations for a PDSE V2 file with member generation support.

    Answering:

    - Each member can have a different number of generations. How would you count number of generations? Do you count all together or use another method? What is the value of having this count? The datasets MAXGEN is all that is required - the information on the individual member generations is not necessary.


    - If a count for each member is being requested then it will not be implemented because LISTDSI works at the dataset level. A count of the number of actual generations would be helpful and yes that would require counting all generations within the PDSE which is probably overkill.

    .Changing status to Uncommitted Candidate. Support would require support from RFE 107052.

    For LISTDSI purposes the MAXGEN info for the PDSE would suffice and be easy to provide.

    As a stretch along with SYSMEMBERS you could provide a count of the number of member generations in the PDSE.

    For example:
    SYSDSNAME: TEST.PDSE
    SYSMEMBERS: 10 (total number of members - gen 0)
    SYSMGENS: 45 (total number of member generations currently in use - gen 1 to n)
    SYSMAXGENS: 20 (maxgens setting)

    We have looked a bit more into this RFE and have some questions.
    - Each member can have a different number of generations. How would you count number of generations? Do you count all together or use another method? What is the value of having this count?
    - If a count for each member is being requested then it will not be implemented because LISTDSI works at the dataset level.
