| SAS/AF Software Procedure Guide |
In addition to other information, CBT, HELP, MENU, and
PROGRAM entries also store attributes that control the appearance and behavior
of the application window in which the entries are displayed to users.
You can specify the following general attributes for CBT, HELP, MENU,
and PROGRAM entries. You define these general attributes in the GATTR window
for the entry. Use the GATTR command in the BUILD procedure's DISPLAY window
to open the GATTR window.
- Window Attributes
- Name
- specifies a window name that is displayed in the window's
title bar when users execute the entry.
- Start row, col
- specify the default position of the upper-left corner of
the application window on the user's display (or within the AWS window, if
application workspaces are used). The default for all entry types is row 1
and column 1. However, the numbers for the default are not displayed in these
fields, and the specification for the starting position is ignored in some
windowing environments.
- Number of rows, cols
- specify the default window height (in rows) and width (in
columns). No default window size values are displayed in these fields in the
GATTR window. The default size depends on your host windowing environment.
Note: You can issue the SETWSZ command in the DISPLAY window to change the
window size while you are building the entry. ![[cautionend]](../common/images/cautend.gif)
- Banner
- specifies the appearance of the entry's command line.
| COMMAND |
provides a command line with the prompt Command===>. |
| SELECT |
provides a command line with the prompt Select Option===> (typically used for
MENU entries). |
| NONE |
disables the command line and the message line as
well.
Note: Messages are not displayed in windows for which you select
the NONE option. In PROGRAM entries, you can use SCL to display messages in
a field.

Note: If you specify a PMENU entry in the Command menu attribute
and the PMENU facility is active, then the specified menu is displayed instead
of a command line.
- General
Attributes
- Help
- specifies the name and type of an entry to display when
users issue the HELP command while the current entry is executing. If you
omit the entry type, the default type is CBT.
Note: Because you can specify
only a one- or two-level name, the entry that you specify must reside in the
same catalog as the current entry.
- Keys
- specifies the name of a KEYS entry that defines function
key settings for the application window. The default is to use the DMKEYS.KEYS
function key entry. You can use the BUILD procedure to create custom function
key definitions for your applications.
Note: Because you can specify
only a one-level name, the KEYS entry that you specify must reside in the
same catalog as the current entry.
- Lookup
data set
- specifies the alias of a field that identifies the data
set that is used to validate fields in a PROGRAM entry when no data set is
specified in the field's List attributes. The Type attribute of the field
that you specify should be set to
Input and
should contain the name of the desired SAS data set, but the AF task does
not verify that these conditions are met.
Note: The Lookup data set attribute
is applicable only to PROGRAM entries.
- Command menu
- specifies the name of a PMENU entry that contains menu definitions
for the application window.
Note: Because you can specify only a one-level
name, the PMENU entry that you specify must reside in the same catalog as
the current entry.
- Prompt
character
- specifies a character that a user can type in a field to
get assistance or information about valid values for the field. A user must
type the specified character in the first position of the field in order for
it to be considered a prompt. The default prompt character is
? (question mark).
The response to the prompt character depends on whether the List attribute
is defined for the field.
- For fields to which a LIST attribute is assigned, a selection
window opens, from which users can choose from the field values defined by
the List attribute.
- For fields to which no LIST attribute is assigned, a dialog box
opens that provides information about the type of values (character or numeric)
that can be entered in the field.
You can prevent the prompting behavior for specific fields
by specifying the NOPROMPT field attribute for the corresponding fields.
The Prompt character attribute applies only to PROGRAM
entries.
- System
options
- control the following window behaviors:
- NO EXIT
- prevents users from switching to other windows. If a user
moves the cursor out of the application window and presses ENTER, the cursor
returns to the application window.
- EXTENDED
TABLE
- specifies that the scrollable portion of a PROGRAM entry's
display is used as an extended table. See Extended Tables for more information about extended
tables.
- RESIDENT
- retains the entry's program in memory after it is first
loaded. Keeping frequently used entries resident in memory can improve the
performance of your applications by eliminating the wait for the entries to
be loaded. However, making a large number of entries resident can cause your
session to run out of memory.
Note: You can use the AFSYS command in
the application window to determine which entries are currently resident in
memory.
- Parent
Attributes
- Name, Type, Libref, Catalog
- specify the name of an entry to which control is passed
when a user issues an END or CANCEL command. By default, control returns to
the calling entry, except for CBT entries, which return control to the SAS
System.
To pass control to another entry in the same catalog as the current
entry, you only need to specify values for the Name and Type attributes. If
the target entry is in another catalog or another library, specify values
for the Libref and Catalog attributes as
well.
- Window Type Attributes
- STANDARD
- specifies that the window can be resized and moved and can
open other windows without passing permanent control to them.
- DIALOG
- specifies that the window cannot be resized or moved. Select
this attribute if you want to prevent users from issuing ZOOM, GROW, MOVE,
or SHRINK commands in the application window. Dialog windows can open other
windows and can pass temporary control to them.
If you assign a PMENU entry to the window, the menu selections are displayed
as a row of buttons at the bottom of the window.
- DIALOG
BOX
- specifies that the window cannot be resized or moved and
cannot open any other windows. Use the DIALOG BOX attribute for the last window
that can be opened in a hierarchy.
If you assign a PMENU entry to the window, the menu selections are displayed
as a row of buttons at the bottom of the window.
- LIST
- specifies that the window can be resized and moved and can
open other windows without passing permanent control to them. Assign this
attribute to windows that are used as selection lists.
If you assign a PMENU entry to the window, the menu selections are displayed
as a row of buttons at the bottom of the window.
- HELP
- specifies that the window can be resized or moved but cannot
open any other windows.
If you assign a PMENU entry to the window, the menu selections are displayed
as a row of buttons at the bottom of the window.
- Scroll Bar
Attributes
- HORIZONTAL
- controls whether a horizontal scroll bar is displayed along
the bottom window border when scroll bars are turned on. Horizontal scroll
bars are useful when the entry's display area is wider than the current window
size.
- VERTICAL
- controls whether a vertical scroll bar is displayed along
the right window border when scroll bars are turned on. Vertical scroll bars
are useful when the entry's display area is taller than the current window
size.
