Updating the SDWA
A recovery routine can update the SDWA in various ways:
- By issuing the SETRP macro (See Using the SETRP macro to update the SDWA.)
- By issuing the VRADATA macro (See the VRADATA macro in z/OS MVS Programming: Assembler Services Reference IAR-XCT and information about symptoms provided by a recovery routine in z/OS MVS Programming: Assembler Services Guide.)
- By directly updating specific fields (see Important fields in the SDWA).
