The CBRUXTVS_EXIT is modeled to interface directly with the ARCTVEXT exit, and therefore supports the ARCTVEXT parameter list. Refer to the z/OS MVS Installation Exits for more information on the ARCTVEXT parameter list. On entry to the exit routines, the Register 1 contains the address of the parameter list which contains the following information:
| Offset | Length or Bit Pattern | Description |
|---|---|---|
| 0 | 4 | The address of an 8-byte data area, where the first 6 bytes contain the volume serial number of the volume having expired, followed by a 2-byte field |
| 4 | 4 | The address of a full word binary return code described below |
