SAS Companion for the CMS Environment

Using the Graphical Interface

The graphical user interface provides windows, commands, and menus that are compatible with 3270 terminals, with 3270 terminal emulation via Emulus, and with other graphics terminals used in the CMS environment. This section describes the ways that SAS windows and window controls function on these terminals.

Window Controls and General Navigation

This section explains some of the basic capabilities of the SAS windowing environment under CMS. The word select indicates a single click of the mouse button. If you do not have a mouse, select indicates that you should position the cursor with the TAB or SHIFT+TAB keys and press the ENTER key.

Function keys

Issue the KEYS command to display and edit function key settings.

Displaying SAS menus

Issue the PMENU command to display the SAS menu bar at the top of each window. Then use function keys or select

Tools Options Command...
to display a command line for a particular window without removing the menus from all windows.

Resizing a window

Select the window border that you want to resize, then select the new position of that window border. Select a top, bottom, or side border to resize horizontally or vertically. Choose a corner to resize horizontally and vertically at the same time. You can also issue the ZOOM, ICON RESIZE, WGROW, and WSHRINK commands to change window dimensions.

Arranging windows

Select

View Change Display
to see a list of window arrangement options. For example, the CASCADE option moves and resizes windows to display the top row of all active windows. You can also issue the RESIZE and TILE commands to arrange windows.

Moving a window

Select the title of the window in the upper-left of the window border. The word MOVE appears in the bottom of the display area. A second click determines the new position of the top left corner of the window, which will not change size. You can also issue the WMOVE command to move a window.

Navigating in a window

Selecting a view: In windows that contain a tree view on the left and a list view on the right, select a view, press the ENTER key, then move the cursor from field to field within that view.
Selecting a field: To select a field in a window, click the left mouse button or press the TAB key to move the cursor, then press the Return key to select a highlighted option.
Selecting a control or widget: With the cursor positioned on a control or widget, issue the WDGNEXT or WDGPREV commands to move to the next, or the previous, control or widget.
Scrolling a view or column: Select a position in the scroll bar to change the displayed portion of a view or column. Selecting in various places causes the display to move up or down one screen width or move to the beginning or end of the view or column.
Resizing a view or column: Select the icon in the right corner of the tree view or column. The view title will change to the resize symbol. Select again to fix the new horizontal position of the corner.
Sorting a column: Select the heading of the column that you want to sort. Not all columns can be sorted.

Selection-Field Commands

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 CMS 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 by 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:

S or X Select or emulate a double-click

? Display context or popup menu

Other selection-field commands are available only in certain windows. Here are some examples:

D Deassign or delete

P Properties

N New

R Rename
