DFSMS ACS variable to recognise a ZFS

It would be helpful if there was an ACS variable to recognise a ZFS dataset in either the &DSNTYPE (as for HFS) or &RECORG read only variables.

ZFS datasets have certain characteristics that need particular kind of management. For example they are mounted so cannot be moved, and may require concurrent_copy for backup. This would help assigning the correct DATACLAS or MGMTCLAS etc. Also, they should not be created on DASD shared between Sysplexes due to each having it's own OAM address spaces that do not communicate, and this could be prevented in the DATACLAS routine if they were recognisable.

    Since discovered that this is available in the &RECORG variable

    Explanation from ISMF :

    Use the RECORG field to specify the data set record organization you want to use in the simulated allocation.

    Possible values:

    KS VSAM Key Sequenced data set

    ES VSAM Entry Sequenced data set

    RR VSAM Relative Record data set

    LS VSAM Linear Space data set

    FS VSAM Linear zFS data set
