CNM* Verbs. Verbs that begin with CNM control the flow of IBM communications
network management (CNM) messages. These are solicited or unsolicited network
management messages conveying information about IBM Systems Network
Architecture (SNA) objects.
The CNMCLEAR verb clears all CNM messages destined for an NCL procedure. The
CNMREAD verb reads the next CNM message destined for an NCL procedure. The
CNMSEND verb sends data from an NCL procedure across a CNM interface. The
CNMALERT verb generates a CNM message and sends it to the system-level
EMSPROC NCL procedure. The CNMVECTR verb splits CNM data into variables.
EMS* Verbs. Verbs that begin with EMS control the flow of Event Management Service
(EMS) messages through the system-level EMSPROC NCL procedure. These are
messages sent to EMSPROC from an EMS distributor.
The EMSALERT verb generates an EMS message to send to EMSPROC. The
EMSCONT verb resumes the normal processing of an EMS message. The EMSDEL
verb deletes the current EMS message. The EMSREAD verb reads the next EMS
message. The EMSSEND verb generates an EMS message to send to an EMS collector.
INT* Verbs. Verbs that begin with INT control the flow of messages sent to and from
dependent processing environments. This is an environment owned and controlled by
an NCL process. The results of commands sent to this environment for execution, by
using the INTCMD verb, are available to the NCL process for processing. Contrast
INTCMD with the CMD core statement described earlier in this section.
The NCL process can read a message using the INTREAD verb, and then either
forward it using the INTCONT verb or delete it using the INTCLEAR verb.
LOG* Verbs. Verbs that begin with LOG control the flow of messages through the
system-level LOGPROC NCL procedure destined for the NonStop NET/MASTER MS
activity log.
LOGPROC can read a message using the LOGREAD verb, and then either forward it
to the activity log using the LOGCONT verb or delete it using the LOGDEL verb.
MSG* Verbs. Verbs that begin with MSG control the flow of messages through the
system-level MSGPROC NCL procedure destined for the OCS window with which the
MSGPROC NCL procedure is associated.
MSGPROC can read a message with MSGREAD, and then either forward it to the OCS
window using the MSGCONT verb or delete it using the MSGDEL verb.
NRDDEL Verb
Another verb used with messages is the NRDDEL verb. This verb is used to delete
non-roll-delete (NRD) messages that arrive at an NCL process.
