 LOADING THE DRIVER
   This driver is a TSR type (Terminate-and-Stay-Resident) program. You
   only need to install it once in memory each time your machine is
   powered up. For this reason, it is recommended that a call to this
   driver be placed in your AUTOEXEC.BAT file. If you are using VersaCad
   5.3 or 5.4 (VersaCad Design), the driver name will be  VC2_911.COM .
   If you are using VersaCad 386, the driver name will be  VC3_911.COM .
 
 
 HIGH LOADING
   For information on loading this driver into the high memory provided
   by certain 386 memory managers, please see the PERFORMANCE TIPS section
   of this manual.
 
 
 EMS MEMORY USAGE
   As a default, this driver will reserve 512K of EMS memory when
   invoked. This will be used to store the display lists needed for fast
   redraws. While this should be enough memory to handle most drawings,
   you can tell the driver to reserve more EMS space when the driver is
   loaded. This is done by setting the environment variable  VCAD_EMS= 
   to the number of EMS pages you whish to have reserved. Each EMS page is
   16K in size.
     Example:
            SET VCAD_EMS=64 
 
   will cause the driver to reserve 1024K (64 pages * 16K) of memory
   when the driver is loaded.
     Example:
            SET VCAD_EMS=0 
 
   will tell the driver to reserve no pages  of EMS for use. This
   special case tells the driver not to reserve any EMS. In this case,
   display list processing will be disabled.
 
 
 
 SCREEN RESOLUTION
   This driver will use the resolution selected by the ENVIRO program.
   If that mode is unavailable, VersaCad will not run.
