SK> Hello again... does anyone out there know how to <maybe in Quick
SK> Basic> change it so instead of having flashing text in text mode you
SK> have hi-intensity backgrounds?  Anyone?

Just happen to have this REAL OLD book - "Graphics for the IBM PC"
ISBN 0-672-22191-8, a SAMS book.

Here it is:
ALL BASIC, but easy to convert-
To enable 16 background colors -  OUT &H3D8,n
 where n is 8 for 40 columns or 9 for 80 columns.
To produce a high intensity background, add 16 to the value of the
forground color when you use the COLOR statement.

To restore your blinking characters and turn off high intensity
backgrounds  -  OUT &H3D8,n
  where n is 40 for 40 column mode and 41 for 80 column mode.

This book was written by Michael Abrash and Dan Illowsky in 1984.
