Indicates the video attribute or color for normal display or for data entry.
Note: Does not apply to SpeedScript programming.
Syntax
COLOR [ DISPLAY ] color-phrase [ PROMPT color-phrase ]
{ field ... } { [ frame-phrase ] }
|
COLOR PROMPT color-phrase
{ field ... } { [ frame-phrase ] }
|
- DISPLAY
- Indicates that you want to use a specific color when the system displays a field.
- PROMPT
- Indicates that you want to use a specific color when the system prompts a user for
input by an INSERT, PROMPT-FOR, SET, or UPDATE statement.
-
color-phrase
- Specifies a video attribute or color. Following is the syntax for
color-phrase:
{ NORMAL
| INPUT
| MESSAGES
| protermcap-attribute
| dos-hex-attribute
| { [ BLINK- ] [ BRIGHT- ]
[ fgnd-color ] [ bgnd-color ]
}
| { [ BLINK- ] [ RVV- ] [ UNDERLINE- ] [ BRIGHT- ]
[ fgnd-color ]
}
| VALUE ( expression )
}
|
For more information on color-phrase, see the COLOR phrase reference entry. ABL ignores the
color-phrase entry for overlay frames on spacetaking
terminals.
-
field
- The name of the field or fields for which you want to override the default colors.
-
frame-phrase
- Specifies the overall layout and processing properties of a frame. For more
information see the Frame phrase reference
entry.
Example
This procedure highlights the item number and on-hand fields for items with an on-hand
value less than 50. The variable hilite holds the video attribute (color) for highlighting.
In this case, the system uses whatever attribute is used for the message area (such as
reverse video, bright, or a color).
r-color.p
DEFINE VARIABLE hilite AS CHARACTER NO-UNDO INITIAL "messages".
/* Use standard messages attribute to highlight OnHand less than 50 */
FOR EACH Item NO-LOCK:
DISPLAY Item.ItemNum Item.ItemName Item.OnHand WITH ATTR-SPACE.
IF Item.OnHand < 50 THEN
COLOR DISPLAY VALUE(hilite) Item.ItemNum Item.OnHand.
END.

Notes
- When the output destination is not the terminal, ABL disregards the COLOR
statement.
- The COLOR statement does not automatically display a frame whose field's color attribute
is changing.
- Use one of these statements to reset a field to the ABL default colors:
COLOR DISPLAY NORMAL PROMPT INPUT field
|
Or:
COLOR DISPLAY NORMAL PROMPT INPUT field WITH FRAME frame
|
- If you run precompiled procedures on a spacetaking terminal, you must specify the frame
field where a color or other video attribute is applied as, or is by default,
ATTR-SPACE.
- If you write a procedure (for a non-spacetaking terminal) that uses color and you run it
on a spacetaking terminal, the AVM does not display the colors. To display the colors, you
must use the ATTR-SPACE option.
- Certain terminals, such as the WYSE 75, are non-spacetaking for some attributes and
spacetaking for others.
- On UNIX, if you specify a color or video attribute that is not defined for the terminal,
the AVM uses normal display instead.
