Allow the LIKE paramenter in JCL to use GDGs or PDS(E) for attributes

Currently to use LIKE in JCL has the following restrictions:

DO NOT use LIKE= to model the characteristics of a PDS member coded in
JCL, a GDG, or a temporary data set. Also, please note that the EXPDT
or RETPD dates are NOT copied by LIKE. LIKE should not be coded on the
same DD statement with the SYSOUT, DYNAM or REFDD parameters.

I would like the LIKE to be able to use a GDG as a model so long as it was created prior to the step it is used in.

Currently if my GDG dataset attributes changes, I have to remember to update everything I do not override as well. With LIKE it would reduce that need.

    Agree it would be nice if relative GDG generations could be used.

    Can't see how temporary files could be used as they're not cataloged, although if they were passed from another step perhaps it could work.

    Can't see how a PDS 'member' attributes could be copied as it would require opening the PDS and the overhead involved. The characteristics of the PDS itself can be copied but has some limitations due to some ACS variables such as &DSORG not being passed to the routines.

    Copying RETPD/EXPDT seems risky as the new dataset may be assigned inappropriate values. Better to get an appropriate DATACLAS with EXPDT/RETPD automatically assigned in the ACS routines based on DSN etc.
