The X Window System is a networked windowing system.
If several machines are linked together in a network, you can run an X application
program, or client, on one machine in the network and display
it on any other machine in the network that is running an X server.
Window managers are X clients that enable you to manage
the windows on a display by moving, resizing, and iconifying the windows.
The Motif interface to the SAS System
can be used with any window manager that is compliant with the Inter-Client
Communication Conventions Manual (ICCCM). Vendors provide at least
one window manager with the X Window System environment.
All window managers perform the same basic functions,
but they differ in their style and in their advanced functions. The appearance
and function of the interface to SAS depends to some extent on your X window
manager. Most window managers provide some kind of frame around a window.
The window manager also governs the placement, sizing, stacking, and appearance
of windows, as well as their interaction with the keyboard.
When you run the SAS System on an X workstation, the
SAS System shares the display with other X applications, including other SAS
sessions. To enable you to distinguish between different applications and
SAS sessions, the SAS System generates a SAS window session ID for each session
by appending a number to the application name, which by default is
SAS. This session ID appears in the window title
bar for each SAS window and in the window icon title. The SAS sessions are
assigned sequentially. Your first SAS session is not assigned a number, so
the session ID is
SAS;
your second SAS session is assigned the session ID
SAS2; and so on. Although the default application name is
SAS, you can use the
-name X option to change the instance name. The instance name can be
up to six characters long.
When you use the SAS System on an X workstation, the
display may be shared by many concurrent applications. When SAS windows from
several different sessions and windows from other applications appear on the
display, the display can become cluttered. To help alleviate this problem,
the windows for a SAS session first appear within an application workspace (AWS). The AWS defines a rectangular region that represents a virtual
display in which SAS windows are initially created. SAS attempts to position
the AWS in relation to the upper-left corner of your display. In other words,
the workspace gravitates toward a certain direction (session gravity) on the display. Some window manager configurations may override the
placement that the SAS System has chosen for a window.
If you issue windowing commands or execute SAS System
procedures that create new SAS windows, the same rules of initial position
and size apply to these windows: they are initially placed in the SAS AWS.
You can use the WSAVE command to save the current window positions (or geometry).
For details, see Customizing Session Workspace, Session Gravity, and Window Sizes.
The SAS System uses primary and interior windows. Some
SAS applications consist of one or more primary windows controlled by the
X window manager in addition to the interior windows controlled by the SAS
System. The SAS windowing environment primary windows, as well as most SAS
application windows, initially appear as top-level windows. Top-level
windows interact directly with the X window manager. They have a full title
bar along with other window manager features. You can manipulate them individually
once they appear on the display. For details about the top-level windows,
refer to the SAS online Help.
Interior windows behave differently than
primary windows. SAS/ASSIST software
is an example of an application with interior windows. Interior windows are
contained within container windows, which may or may not be primary
windows. Sample Interior Window
shows an interior window in SAS/ASSIST software.

The SAS System provides some
degree of window management
for interior windows. Specifically, interior windows have the following sizing
and movement capabilities:
