Microsoft Basic
MS-BASIC
    (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.
