WHAT IS WATCOM?
===============
WATCOM is a set of compilers and tools for developing software in the
Fortran, C, and C++ programming languages. It was originally
developed by the Watcom International Corporation in the 1980s and
1990s.

WATCOM was widely used for developing software for DOS and Windows.
It supported DOS, extended DOS 32-bit, Win16, Win32, and OS/2.

Although their products are discontinued in the 2000s, WATCOM C/C++
compilers are still available under the name of open WATCOM in the
GitHub.

The story of WATCOM begins with a computer scientist at University of
Waterloo, Wes Graham. In 1974, Wes Graham and Ian McPhee founded a
company named Structured Computing Systems. The company soon changed
its name in 1981, to WATCOM Systems Inc. With three full-time
employees, the history of WATCOM began. WATCOM had several subsidiary
companies, but they were all renamed as WATCOM companies for branding
purpose. After 1984, the company named itself WATCOM International Inc.

WATCOM was an efficient c/c++ compiler. In the 90s, the capability of
WATCOM compiler caught 3D game developers' attention. Plus, WATCOM
compiler performed much faster than its competitors, Microsoft and
Borland. Amongst many games that used WATCOM, we will name a few that
you have certainly heard if you like video games: Doom and 3D Realms.
The product was also shipped with popular DOS extender DOS/4GW.
