CLR & COLOR
-----------
Purpose: COLOR sets the screen color attribute without overwriting
the screen. CLR (for "CLEAR") clears the screen, sets the
active page to 0, and sets the screen color attribute.
Format: CLR [ss[,bb]]
or
COLOR [ss[,bb]]
where ss is the number (in decimal) of the screen attribute,
and bb is the number of the border color.
Remarks: If no attribute is given, both CLR and COLOR default to #7,
white on black.
If attribute but no border color is given, the border will
match the background of the screen.
0 (black on black) is not accepted as a screen attribute, but
you can call for a 0 (black) border.
Thus: COLOR 2 turns the screen (with what's on it) to green
on black. CLR 96 clears the screen and turns it black on
brown with a brown border. COLOR 96,2 produces a black on
brown with a green border. CLR clears the screen and turns
it white on black.
NOTES:
1. COLOR works only on the first page (0) of the CGA.
Dunno what it would do on an EGA, but it does nothing
on a mono Text monitor.
2. CLR works on both CGA and the mono Text Monitor.
3. If you need help finding attribute numbers or chosing
your colors, try COLRBITS
