 operating system. The Watcom C/C++ compiler with QNX developed a market for embedded applications.

In 1988, Watcom released their first C compiler for the IBM PC platform (and compatibles). It was released with a version number of 6 at a time when the latest version numbers of Borland's and Microsofts C Compilers was version 5. These version numbers signified nothing and were used for marketing purposes. The compiler could create tighter and faster code than its competition.

In 1992, Watcom began a move into the client-server arena with the introduction of Watcom SQL
