Subsystem request type specification - Key = '0062'
DALSSATT specifies that the subsystem data set being requested is to be allocated to SYSIN. The subsystem request key (DALSSREQ) is required with this key.
Note: To specify DALSSATT, you must be APF-authorized, or
in supervisor state, or running with PSW key 0 - 7.
When you code DALSSATT, # and LEN must be one, and PARM contains '80', for SYSIN data set.
Example: To specify a subsystem SYSIN data
set, code:
KEY # LEN PARM
0062 0001 0001 80
