NonStop NET/MASTER MS SHUTDOWN command. This command affects all
users and requires an authority level of at least 4.
NCL processes executed within a region affect only the user that owns the
environment.
This prevents one user from affecting or tampering with NCL processes in use by
another user. The settings of system parameters, such as SYSPARMS NCLXUSER,
affects the ability of some NonStop NET/MASTER MS commands and command
operands to cross a region boundary. An example is the INTQ command,
described later in this section.
Environmental Scope and Hierarchy
Figure 16-1 shows the regions of two real users, NNMJPN and NNMDGS, in which the
former is logged on twice. The activities of each user are clearly bound by their
regions. Available activities include choosing options from the primary menu,
displaying panels, and executing NonStop NET/MASTER MS commands and NCL
procedures.

Figure 16-2 illustrates the concept of scope in more detail. It shows that, within each
region, there are two top-level environments and that, below each top-level
environment, there is one primary processing environment. Each primary processing
environment is associated with an OCS window (OCS window 1 and OCS window 2).
NonStop NET/MASTER MS commands and NCL procedures executed from an OCS
window run in the primary processing environment associated with that window.
The OCS command input line prompt is => (and can be preceded by mode indicators,
such as A, P, and M: for example, APM=>). You can execute any NonStop
