Alter the options with a TRACE ST operator command.

- PR
- pr: Identifier of the processor that produced the
TTE.
- ASID
- home: Home address space identifier (ASID) associated
with the TTE.
- TCB-ADDR
- tcb-addr: Address of the task control block (TCB)
for the current task or the work element block WEB).
- IDENT
- The TTE identifier, as follows:
- ALTR
- Alteration of the trace option. An asterisk (*) always appears
before ALTR to indicate an unusual condition.
- CD/D

- UNIQUE-1/UNIQUE-2/UNIQUE-3
- UNIQUE-4/UNIQUE-5/UNIQUE-6
- tobtropt: Trace options in control register 12 format,
from the TOBTROPT field of the system trace option block (TOB)
- gpr0----: General register 0
- gpr1----: General register 1
- pol-: The number of processor with tracing active
or suspended, from the TOBTRPOL field of the TOB
- buf-: The number of trace buffers per processor, from
the TOBTRBUF field of the TOB
- PSACLHS-
- Blank
- PSALOCAL
- Blank
- PASD
- pasd: Primary ASID (PASID) at trace entry.
- SASD
- sasd: Secondary ASID (SASID) at trace entry.
- TIMESTAMP-RECORD
- timestamp-------: Time-of-day (TOD) clock value
when system trace created the trace entry. The value is in the same
format as the time stamp on logrec data set records.
- CP
- The CP column contains 2 hex digits of the processor model dependent
information, which is intended to identify the physical CP that made
the trace entry. CP is only provided when formatting SYSTRACE under
IPCS. CP is not provided for SYSUDUMP, SYSABEND, or SNAP.
