Code DINRGDGO to request the return of the order in which the individual
generation data sets (GDSs) are concatenated.
When you code DINRGDGO, # must be 1, LEN must be 1, and upon return,
the PARM value will contain one of the following values:
- X'80'
- USECATLG – The GDS concatenation is ordered as specified in the
GDG data set catalog entry.
- X'40'
- LIFO – The GDS concatenation is ordered with the newest GDS defined
first and the oldest GDS last.
- X'20'
- FIFO – The GDS concatenation is ordered with the oldest GDS defined
first and the newest GDS last.
Example: To request the return of the specification of GDGORDER
on a batch or dynamically allocated DD which specified GDGORDER=FIFO
on the request, code:
Input:
KEY # LEN PARM
C02E 0001 0001 00
Output:
KEY # LEN PARM
C02E 0001 0001 20
Note: For this text unit, the information specified by
the user in JCL or via dynamic allocation text units is retrieved
via the Scheduler JCL Facility (SJF). If the information was not available,
no information is returned. Also, this key does not return the value
of the GDG order setting in the catalog entry for the GDG.
