There is a programming interface called XVT (eXtensible Virtual Toolkit)
which allows you to develop window system independant applications for
Mac OS/Windows 3.0/PM for OS/2/PM for CTOS/Motif on many
platforms/Character based screens under DOS OS/2 and Unix.  Although it
has some short comings it has some very nice features:

	- Event handling
	- Multitasking
	- Different styles of Windows (multiple document windows vs. a single
	  application window)
	- Printing functions
	- Clipboard functions
	- Normal drawing primitives
	- Intelligent font handling
	- Support for pictures (PICT on mac, .BMP for windows, .xbm for
	  Motif) Better support is slated for later issues.
	- System independant Resource files
	- Help system
	- Allows window system specific extensions
