Well, let's not jump to conclusions here. Since you haven't written any Eiffel, then you haven't used the graphics class library either. You might want to look at it before you decide whether or not to base your decision to use Eiffel on whether that particular library is portable! (Also, the current graphics library depends on X, so it would have to be modified to sit on Windows 3.0, and use on the Mac would require X, or it would have to be modified to use the Toolbox.) ISE's original plans, as I recall, call for a, what you might call "technology independent" graphics library, but they're not quite there. -- Jim Gish (jgish@gte.com) Principal Investigator Software Reusability Project GTE Laboratories Inc.
