GTF builds SVC comprehensive records when an SVC interruption occurs and either the TRACE=SYS or TRACE=SVC GTF option is in effect. All SVC records contain the basic data described below; however, many SVC numbers invoke additional data recording, described following the basic data.
The FID for the SVC comprehensive trace record is X'010'. The EID is X'1000'.
| Offset | Size | Description |
|---|---|---|
| 0 (0) | 4 | ASCB. |
| 4 (4) | 2 | CPUID. |
| 6 (6) | 8 | Job name. |
| 14 (E) | 16 | SVC old PSW. The seventh and eighth bytes contain the SVC number. |
| 30 (1E) | 4 | Old TCB. |
| 34 (22) | 8 | CDE name. |
| 42 (2A) | 4 | Register 15. |
| 46 (2E) | 4 | Register 0. |
| 50 (32) | 4 | Register 1. |
