**	MS-DOS Constants.
**
**	There are 3 different sets of MS-DOS constants defined here.
**	Those for Microsoft C (#define MSC), those for Borland C/Turbo C
**	(#define TURBOC), and a generic set. If neither MSC nor TURBOC
**	are defined then the generic set of constants will be used.
**
**	No "MALLOC" ( or "FREE" ) functions are defined in the generic
**	version, hence attempting to compile this version will produce
**	errors. The generic version uses ansi video routines which should
**	work with most MS-DOS ANSI.SYS files. If your ANSI.SYS does not support
**	the <ESC>[nJ sequence, then "SIMPLE_ANSI_ESCAPE" should also be defined.
**
**	Windowed scrolling is implemented using the INT 10h interrupt
**	function in "msdos_putchar()". This is done using the "int86 ()"
**	function defined in <dos.h>:
**
**		int
**		int86 ( intno,inregs,outregs )
**		int			intno ;
**		union REGS	*inregs ;
**		union REGS	*outregs ;
**
**	If your compiler does not support these features, please add an
**	extra definition rather than modifying the generic definition.
