In a stand-alone dump taken after a SLIP ACTION=WAIT trap matches, problem data can be found in a work area pointed to by the PSAWTCOD field in the prefix save area (PSA). Table 1 shows the format of this area.
| Offset | Length | Content |
|---|---|---|
| 0 (0) | 1 | RTM/SLIP processing environment indicator:
|
| 1 (1) | 2 | Logical processor identifier (CPUID) |
| 3 (3) | 1 | System mask, if offset 0 is 2 (RTM2) |
| 4 (4) | 4 | Pointer to general purpose registers 0 through 15 at the time of the event |
| 8 (8) | 4 | Pointer to the 16-byte program status word (PSW) at the time of the event |
| 12 (C) | 4 | One of the following, as indicated by the RTM/SLIP processing
environment indicator at offset 0 of the work area:
|
| 16 (10) | 4 | Pointer to cross memory information (control registers 3 and 4) at the time of the event |
| 20 (14) | 4 | Pointer to access registers AR0 through AR15 at the time of the event. Pointer to the high 32 bits of the 64-bit GPRs, or 0 if not available. See Wait State 01B in the z/OS MVS System Codes for more information. |
