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.
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. A common window manager is the Common Desktop
Environment (CDE). If you are using another window manager such as the Tab
Window Manager (twm), you should also read the documentation that is supplied
by the vendor for that window manager.
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). See Customizing Session Workspace, Session Gravity, and Window Sizes for details.
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 decorations. You can manipulate them individually once they appear
on the display. For details on the top-level windows, refer to the online
help.
Interior windows
behave differently than primary windows.
SAS/ASSIST software is 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:
