Insulated DD request - Key = '0079'

DALINSDD indicates that the insulated DD attribute is to be assigned to this allocation.

For a description of this key, see Insulated DD attribute. When you code this key, # must be zero, and LEN and PARM are not specified.

DALINSDD is mutually exclusive with the DALCNVRT (X'0053') and DALCLOSE (X'001C') text units.

Use of DALINSDD implies that the DD is permanently allocated.

This text unit is available on z/OS® 1.13 and later systems with APAR OA47824 installed. When this support is available, the JESIBSAV flag in the JESCT is on. See the IEFJESCT macro for usage in formation.

Note: To specify DALINSDD, your program must be APF-authorized, in supervisor state, or running with PSW key 0 - 7.

Example: To specify assignment of the insulated DD attribute, code:

KEY   #     LEN      PARM
0079  0000  -        -
