Table 16-4 summarizes how the environment in which a NonStop NET/MASTER MS
command is executed affects where the results of the command are sent. It also shows
the owner of each type of current execution environment.

Windows and Top-Level Environments
NonStop NET/MASTER MS has two windows available for each user who logs on.
Each window has a number (1 or 2), each window is referred to by its number
(window 1 or window 2), and each window keeps its number while a user is logged
on, regardless of the activity that takes place.
Window 1 is created automatically when a user logs on: by default, when a user logs
on, NonStop NET/MASTER MS displays the NonStop NET/MASTER MS primary
menu in window 1. Window 2, however, is not created automatically. The window is
created on the first occasion a user swaps from window 1 or splits the screen from
window 1: by default, when created, the NonStop NET/MASTER MS primary menu
is displayed in window 2.
Note A window is created by being displayed on the screen. A window that has been displayed at least once
on the screen is called an open window. A closed window is a window that has not been displayed at all
on the screen. However, an open window may not always be visible on the screen: for example, when
using two full-screen windows and swapping between them, only one window can be displayed at a time.
