ARCRPEXT—Output Data Structure

The third word of ARCRPEXT Parameter List points to the area described in Table 1.

Table 1. ARCRPEXT Output Data Structure
Offset	Length or Bit Pattern	Description
00 (X'00')	4	Binary return code from exit ARCRPEXT. See ARCRPEXT Return Codes.
04 (X'04')	1	A flag byte containing the following bits: 0... .... Use default priority for NOWAIT requests. 1... .... Use priority at offset 06 for NOWAIT requests (if return code does not request a purge). .0.. .... Default - no change to DFSMShsm processing. .1.. .... Do not force extent-reduction recall to the original source volume. ..xx xxxx Reserved.
05(X'05')	1	Reserved.
06 (X'06')	2	Desired binary priority for the request. DFSMShsm initializes this field with either a default value of 50 or the priority value (for a data set recover request initiated from a volume recover request) propagated from the initiating volume request.
08 (X'08')	4	Address of an area where your exit can construct messages for DFSMShsm to write to the pertinent activity log. See ARCRPEXT Message Area.
