Maximum PDSE Generation - Key = '802D'
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.
