Brighter background colors

[Robert E. Carneal]

In PB 3.5 for Dos, is it possible to make a background of
brighter colors, *AND* have text in it?

For example, can I have a background of bright white with
blinking red text to say: "Note: Payment Missed" ? Yes, I am
familiar with COLOR, but I don't think the background color goes
above color #7 (white), or does it? Please don't hammer me; I don't
think it can be done but others are saying that it can.

Thank you.

This is a snippet of code from M$ Basic 7 to reprogram the palette.
As I understand it, PBDOS should be able to do something similar.
You will need a UDT for the regs. (Or write it in Inline assembler)

dacreg% = BLUE
redval% = 0
greenval% = 0
blueval% = 15
'
inreg.ax = &H1010                       'set colour register dacreg%
inreg.bx = dacreg%
inreg.dx = redval% * 256                'dh = red value
inreg.cx = (256 * greenval%) + blueval% 'ch = green value, cl = blue value
CALL interrupt(&H10, inreg, outreg)

I'm not sure that palette reprogramming will work in text mode, but it may
be worth a shot. There's another way of doing it that involves using the
"blink" bit to mean "bright background": INT &H10, AX = &H1003, BL = toggle.
This won't allow you to combine bright white with blinking red, though:
you can have either bright backgrounds or blinking, but not both. Of course,
you could always do the blinking "manually" with a timer.

Works OK in text mode in M$B7!
Note that the limit appears to be 64 levels per color (0 to 63) giving a possible 262,144 shades. Also they do not have to be related to the original color, I usually remap Magenta (ugh!) & Light brown to something more tasteful.

Hello Egbert-

I went to URL:

but did not see the file you suggested. Did I go to the correct
place?


Thank you.
