- microsoft basic — (language) (MS-BASIC) A dialect of BASIC from Microsoft, originally developed by Bill Gates in a garage back in the CP/M days. It was originally known as GWBasic, then QBASIC and finally MS-BASIC. When the MS-DOS operating system came out, it incorporated the GWBASIC.EXE or BASICA.EXE interpreters. GWBASIC ("Gee Whiz") incorporated graphics and a screen editor and was compatible with earlier BASICs. QBASIC was more sophisticated. Version 4.5 had a full screen editor, debugger and compiler. The compiler could also produce executable files but to run these a utility program (BRUN44.EXE) had to be present. Thus source code could be kept private. From DOS 5.0 or 6.0 onward, MS-BASIC was standard. Version 1.1 produced stand-alone executables and could display graphics.
