    DEC COBOL supports X/Open SCREEN SECTION on
    
    	OpenVMS Alpha
    	DIGITAL UNIX
    
    This includes some support for
    
>                 [ FOREGROUND-COLOR IS color-num-1 ]
>                 [ BACKGROUND-COLOR IS color-num-2 ]
    
    See the DEC COBOL Reference Manual (Data Division - Screen Section) and
    User Manual (chapter on ACCEPT/DISPLAY) for more details.

3224.2ANSI Standard color sequencesPACKED::BRAFFITTWed Apr 09 1997 12:206
    Also note that FOREGROUND-COLOR and BACKGROUND-COLOR are implemented
    using ANSI Standard color sequences.  Some workstations and terminals
    support these sequences.  The VT100/200/300/400 series terminals do NOT
    support these sequences.
