Improve Readability of Menus On Personal System/2 Displays

       This programming technique allows the IBM 3270 Emulation
Program to improve the readability of its menus on black and white
Personal System/2* (PS/2*) displays.

      This problem was solved by taking advantage of a function that
the the 3270 Emulation Program provides which allows the user to
change the screen mode from color to black and white, and vice versa,
via a menu item on its Request Tasks Menu.  A flag is used to
indicate to the display access method routines that the menus should
be displayed in color or in black and white.

      The solution to this problem was to simulate a screen mode
change to black and white mode if a black and white Personal System/2
display is the primary display.

      The following items illustrate how the 3270 Emulation Program
implemented this programming technique.
1.  During initialization, two flags are set if a black and white
PS/2 display is the primary display.  Flag 1 indicates that a black
and white PS/2 display is active.  Flag 2 indicates that the screen
mode is set to black and white mode and is used by the display access
methods to determine whether or not to display the menus in color or
in black and white.
2.  In the Request Task menu routines, Flag 2 is turned off only if
the screen mode item has been selected and if a black and white PS/2
display is NOT active (as indicated by Flag 1).  This allows the
screen mode to change if a...
