(MS-BASIC) A dialect of BASIC
, 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.
Latest version: 1.1, also produces stand-alone
executables and can display graphics. Usenet
