ARC6084E

Explanation
 A VSAM data set has been encountered in the ABACKUP
ALLOCATE list during ABACKUP processing. The possibility exists that
the attributes of this data set may change as a result of ARECOVER
command processing. The ABACKUP RETURN CODE, appearing in message
ARC6055I, is set to 084.

System action
 DFSMShsm processing continues. Issued
By: ABARS secondary address space.

Programmer response
 This message is intended to warn that the
attributes of the VSAM data set could change during ARECOVER processing.
This potential problem can be avoided by including all VSAM data sets
in the ABACKUP INCLUDE list instead of the ALLOCATE list.
 A
patchable bit in the ABRCB, when set ON, prevents the ABACKUP RETURN
CODE from being set to 084 when VSAM data sets are encountered in
the ABACKUP ALLOCATE list. For example,  PATCH .ABRCB.+81 BITS(........1)
