Is proud to offer you this anthology of utilities for IBM-PC users
with both color and monochrome monitors. These utilities will allow you
complete use of both of your monitor for the temporary storage of screen
information. The library consists of the following files:
FLIP.COM Allows you to switch active pages on the color screen.
FLIP.ASM Source code for above
DOORS.COM Resident program that switches active displays
X2COLOR.COM Copies contents of monochrome screen to color screen
X2MONO.COM Copies contents of color screen to monochrome screen

FLIP:
Written by K Scott Hunzliker, Cambridge, Mass.
Appeared in Volume 4, Number 4, PC Magazine, pp 256-257
FLIP.COM is for use while the color display is active. Each time it is
executed it toggles the active page between page 0 and page 1 (without
altering the screen contents) thus doubling the amount of information that is
available for display on the color screen. This program has no effect when the
monochrome display is active, and may be used on systems that use the color
display exclusively. The source code, FLIP.ASM, has been included in this
library, so that others may consider employing this technique in subsequent
programs.
DOORS:
Written by John Dickinson
Appeared in Volume 4, Number 3, PC Magazine, pp 273-277
DOORS.COM is a resident version of the DOS MODE command. Whenever the Alt and
Right Shift keys are pressed, the other display to becomes active. It
also copies the contents of the original screen to the new active display.
DOORS will not allow you to switch to the monochrome display if the color
display is in graphics or 40 text column mode, but you may switch to the color
monitor at any time. Only run DOORS once; the only way to remove it is by
rebooting the system. DOORS is compatible with most programs except those
that insist on writing to the original screen like 123 and WordProof.
Programs that have their own keyboard interrupts will not work with DOORS.
X2COLOR and X2MONO:
Written by Jeff Garbers
Uploaded to The Consultants' Exchange BBS
X2COLOR.COM will instantly copy the contents of the monochrome screen to the
color display without changing active displays. The color display must
first have been initialized by another program or the DOS MODE command.
X2MONO.COM copies the contents of the color screen to the monochrome display.
