Specifies a video attribute or color. In Progress Version 7 and later, the COLOR phrase is superseded by the FGCOLOR and BGCOLOR options in graphical user interfaces and by the PFCOLOR and DCOLOR options in character interfaces. The COLOR phrase is supported only for backward compatibility.

Windows — On a color monitor, the default colors are a blue background and a white foreground. On a monochrome monitor, the default colors are a standard background and foreground, depending on the monitor.
|
|
|
UNIX — The default colors are the normal display mode of your terminal.
|
|
|
Windows — On a color monitor, the default colors are a light gray background and a blue foreground. On a monochrome monitor, the default underlines fields that require input.
|
|
|
UNIX — The default colors depend on the type of terminal and how INPUT is defined in the protermcap file, but it is usually underlining.
|
|
|
Windows — On a color monitor, the defaults are the same as for INPUT. On a monochrome monitor, the default is reverse video.
|
|
|
UNIX — The defaults depend on the type of terminal and how MESSAGES is defined in the protermcap file, but it is usually reverse video. (The protermcap file supplied with ABL supplies default attributes for NORMAL, INPUT, and MESSAGES for all defined terminals.)

You use the protermcap-attribute option only if you are using UNIX. This is the name assigned to the attribute in the
protermcap file (for example, RED, BLINK, etc.). See
OpenEdge Deployment: Managing ABL Applications for a description of the
protermcap file.

If fgnd-color is omitted, then the system uses the foreground corresponding to NORMAL. If
bgnd-color is omitted, then the system uses the background corresponding to NORMAL. If NORMAL, INPUT, or MESSAGES is specified for
fgnd-color or
bgnd-color, then the system uses the foreground or background color of the specified standard color.

The following procedure displays a random number of asterisks, in a random color, column, and row in 10 different occurrences. The COLOR statement displays the asterisks in one of the three colors stored in the elements of the hilite array. The COLOR phrase in this example is VALUE ( hilite[ RANDOM( 1,3 ) ]. The DISPLAY statement uses the color determined in the COLOR statement to display a random number of asterisks.
