Return IEFOPZ-New data set name - Key = '007C'
DALRetIEFOPZNewDSN requests that the IEFOPZ-New data set name from IEFOPZ processing be returned to the caller.
When you code this key, # must be 1, and LEN must be at least the length of the dsname (and can be longer, up to a maximum of 44 characters). The PARM field must be the length specified by the LEN value.
Dynamic allocation places the allocated dsname in PARM and updates LEN to the length of the returned dsname. If no IEFOPZ-New data set was added, the # field is set to 0 on output, and the LEN and PARM fields contain no valid data.
Example: To request that IEFOPZ-New
data set name be returned, code:
KEY # LEN PARM
007C 0001 002C --------If an IEFOPZ-New data
set is processed, this specification is updated for the allocation
of the dsname ABC, as follows:
KEY # LEN PARM
007C 0001 0003 C1C2C3If an IEFOPZ-New data
set is not processed, the specification is updated, as follows:
KEY # LEN PARM
007C 0000 ???? ????????????
