&$CNMHLU, &$CNMHTPU, &$CNMHPU, &$CNMHLNK and &$CNMHSPU
contain hierarchy information concerning the originating device. Each
variable that is set contains the eight-character name of the resource (in
EBCDIC) and a type code that may be:
Type Code Description
CHAN Local channel link.
CPU Host.
CTRL PU or control unit.
DEV Device.
LINE Telecommunications line on an NCP.
LKST Link station.
NCP NCP PU.
If the NSRU originated from a logical unit (LU), then &$CNMHLU is set;
otherwise, &$CNMHTPU contains the target physical unit (PU)
information. &$CNMHPU is the controlling PU name and type (which
may be the same as &$CNMHTPU), &$CNMHLNK contains the PU’s link
information, and &$CNMHSPU contains the PU’s boundary function PU
information. These variables are set only when information is available.
&$CNMMVCNT
contains, for NMVT records, the number of major vectors present in the
record. If this variable is greater than 1, use the CNMVECTR verb to
obtain access to the remaining major vectors.
&$CNMMVLEN
contains the binary length of the currently vectored major vector (MV).
&$CNMMV nn
contains the major vector of the nn th MV. nn is the number of the MV.
&$CNMMVTYPE
contains the major vector type (such as “0025”x, “0080”x, and so on) of the
MV.
&$CNMNSRU
contains the embedded Network Services RU (NSRU). For an NMVT RU,
it contains only the first 12 bytes. For a RECFMS (record formatted
maintenance statistics) Type 0 message, it contains only the first 20 bytes
of the RU. The remainder of these RUs consist of various CNM subvectors
that are available in separate variables.
