| SAS Companion for the OS/390 Environment |
The graphical user interface provides
windows, commands,
and menus that are compatible with 3270 terminals, with 3270 terminal emulation,
and with other graphics terminals used in the OS/390 environment. This section
describes the ways that SAS windows and window controls function on these
terminals.
For information on hardware support for terminals and
mouse input devices, see Terminal Support in the OS/390 Environment.
This section explains
some of the basic capabilities of the SAS windowing environment under OS/390.
The word select indicates positioning the cursor with a single
click of the mouse button or with the TAB or SHIFT+TAB keys if you don't have
a mouse. Press the ENTER key to confirm your selection. The word choose refers to the selection and confirmation of a menu

Selection
fields allow you to accomplish tasks in windows using keystrokes or mouse
clicks. This section introduces the selection-field commands that are generally
available in the OS/390 windowing environment.
Certain SAS windows display a tree view on the left
and a list view on the right. Each view has its own set of selection-field
commands. (You may wish to display one of these windows to test the following
commands.)
The tree view shows hierarchical structures
such as SAS
libraries and members. To display or hide a level of detail, position the
cursor on the plus sign (+) or the dash (-) to the far left of the library
or member name and press the ENTER key. A single mouse click does the same
job.
In the
tree view and list view, you may perform tasks
using the selection field represented by an underscore character (_) just
to the left of the item. To issue selection-field commands, select the selection
field and press ENTER to display a menu (or use the WPOPUP command), or simply
type the single-character command and press ENTER. This first set of commands
is available in all selection fields in all windows:
Other selection-field commands are available only in
certain windows. Here are some examples:
