MWRGB_DB
The MWRGB_DB variable specifies the full pathname to the file rgb.txt, which 
maps color names to 24-bit RGB color values in the X server. If MWRGB_DB is 
not used, the program looks for rgb.txt in the following directories, in order:
1. /usr/openwin/lib
2. /lib
3. /usr/X/lib
4. /usr/lib/X11
MWSCREEN_HEIGHT & MWSCREEN_WIDTH
The MWSCREEN_HEIGHT and MWSCREEN_WIDTH variables control the literal 
size of objects on the screen. They can be set to the actual screen height and 
width of your display, in millimeters. The default values are those of the X 
server.
MWSYSTEM_FONT
The MWSYSTEM_FONT variable specifies the default system font used by 
MAX+PLUS II. If this variable is not used, the default font is Helvetica. To 
change the system font, set this variable to an existing X font name. For more 
information, see ÒFontsÓ on page 292.
MWUNIX_SHARED_MEMORY
The MWUNIX_SHARED_MEMORY variable determines whether or not 
MAX+PLUS II may use UNIX shared memory when it shares data with 
another program.
If MWUNIX_SHARED_MEMORY is set to true, MAX+PLUS II can use UNIX 
shared memory, which may improve its speed performance. If it is set to 
false (the default value), MAX+PLUS II uses shared memory in the 
X server when it shares data with another program. This shared memory 
allows data exchanges between programs that run on different machines, 
but which are displayed on the same X server.
