You can use the SHOW SYSPARMS command to display the name of the current
EMSPROC NCL procedure. You can use the STATUS command to determine whether
EMSPROC is running. The following screen displays the name and status of
EMSPROC:

Verbs Used by EMSPROC to Process Messages
EMSPROC uses the following three verbs to read, forward, and delete the messages it
receives. Only an EMSPROC NCL procedure can use these verbs. These verbs are
discussed later in this section.
EMSREAD
EMSCONT
EMSDEL
The LOGPROC NCL
Procedure
The function of the LOGPROC NCL procedure is to intercept and process messages
destined for the NonStop NET/MASTER MS activity log. The LOGPROC NCL
procedure runs under the control of the Activity Log Process (LOGP) virtual user.
The NonStop NET/MASTER MS activity log represents a serial record of all activity in
a NonStop NET/MASTER MS system. The PARAM pLGFILE1 command defines and
names the activity log file used by NonStop NET/MASTER MS during NonStop
NET/MASTER MS startup. (The letter p represents the name of the unique NonStop
NET/MASTER MS process character.) The SYSPARMS LOGFILEn command defines
and names each file that is available for use in the group of activity log files after
NonStop NET/MASTER MS startup. (The letter n represents the number of an
activity log file in the group.)
Although you can open and close activity log files as required, by using the
LOGSWAP command, there is only one activity log available for use at a time in a
