4 4 Unsigned 1 MRHDRDM domain identifier
5 5 Unsigned 1 *
6 6 Unsigned 2 MRHDRRC record identifier
8 8 Character 8 MRHDRTOD Time at which this record was
built. In time-of-day (TOD) clock
format. See IBM System 370 XA
Principle of Operation for
explanation of format.
16 10 Character 4 *
20 14 Character 0 MRHDR_END End of header
20 14 Bitstring 8 MTRSYS_HCPCPEPP Program product bit map. This is
a CP internal indicator of release
level of the program product. For
the meaning of the bit map, see
the output descriptions of
Diagnose X'00' in the CP
Programming Services manual.
28 1C Character 8 MTRSYS_HCPCPEID Version number, in EBCDIC
format. Byte 0 = release number.
Byte 1 = modification level
number. Bytes 2-3 = version
number. Bytes 4-7 = service level.
36 24 Character 8 MTRSYS_SYSTODST TOD clock at last IPL

68 44 Unsigned 4 MTRSYS_SYSVFCVM Map of the connected vector
facility
72 48 Unsigned 4 MTRSYS_SYSVFIVM Map of the installed vector
facility
76 4C Unsigned 4 MTRSYS_SYSVFOVM Map of the operational vector
facility
80 50 Unsigned 4 MTRSYS_SYSZONE TOD clock time zone facility
differential. Add this to a TOD
time stamp to get the local time.
The units here are seconds.

Registers) is installed
.1.. .... MTRSYS_CALADMF Asynchronous Data @VR4GDVS Mover
Installed
..1. .... MTRSYS_SYSDVACT Subchannel-Device-Active-Only

- this means that the hardware is
accumulating device-active-only
measurements as opposed to CP
calculating them manually

nucleus.
