|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

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
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 an item. To issue selection-field commands, position the cursor
and type in a single character, some of which are listed below, or issue the
WPOPUP command (mouse button 2 by default) or a question mark (?) to see a
menu of available selection field commands.
