Reason Codes from Dynamic Allocation

When a DAIR return code of 12 is returned, the codes returned in the DAxxDARC field of the DAIR parameter block are the dynamic allocation error reason codes. See z/OS MVS Programming: Authorized Assembler Services Guide for explanations of dynamic allocation error reason codes. In addition to those codes, which are converted from dynamic allocation codes back to the same codes which were used in previous releases, the following reason codes can also be returned:
