Maximum PDSE Generation - Key = '802D'

When you have applied APAR OA42358, DALMAXG specifies the maximum number of PDSE member generations to be retained by the system.

When you code DALMAXG, # must be 1, LEN must be 4 and the PARM field contains a value between 1 and 2,000,000,000.

Example: To specify 255 as the maximum number of PDSE member generations (DALMAXG) for the DD statement with name DD1, code:

Key   #     LEN   PARM                                             
0001  0001  0003  C4 C4 C1                                         
802D  0001  0004  000000FF

In this example, the data set type represents a library (PDSE) version 2.

Note: DALMAXG is relevant only for data sets of type LIBRARY. You may need to specify DALDSNT to set the DSNTYPE.
