__FB_DOS__

Intrinsic define set by the compiler

Syntax
	__FB_DOS__

Description
	Define without a value created at compile time if compiling for the DOS 
	target. Default in the DOS hosted version, or active when the CompilerOpttarget-target dos
	command line option is used. It can be used to compile parts of the 
	program only if the target is DOS. Note: the DOS hosted version cannot 
	compile to other targets than DOS by now.

Example
	#ifdef __FB_DOS__
	  ' ... instructions only for DOS ...
	  ' ... INT 0x31
	#else
	  ' ... instructions not for DOS ...
	#endif
