     NATICK, Mass., September 10, 1993 -- Rational Systems today announced
an upgrade to DOS/4GW, the DOS extender included with the WATCOM C/C++(32)
and FORTRAN 77(32) programming languages. DOS extenders allow 32-bit
programs to run on Intel 386 processors (and compatibles) under DOS, in an
OS/2 2.x DOS box, in a Windows 3.x DOS box, or in a Windows NT DOS box.

     DOS/4GW Professional adds performance enhancements for demanding
applications, and the ability to bind the DOS extender to the application.
 DOS/4GW programs do not need to be recompiled or relinked to take
advantage of the upgrade.

     DOS/4GW Professional includes a high-performance virtual memory
manager and will demand-load applications.  Almost all DOS/4GW
applications that utilize virtual memory will load and run significantly
faster under DOS/4GW Professional.  In addition, DOS/4GW Professional is
approximately 50K smaller in memory and on disk than DOS/4GW.

     DOS/4GW Professional, with unlimited royalty-free distribution, is
available for $298 from Rational Systems, 220 N. Main St., Natick, MA
01760; telephone (508)653-6006
