	If you set _ERRORCHECK_, you need to recompile Math881. To
do this:



	- open the Math881 project
	- hold the Option key, press the mouse in the title bar
		of the project window, and pull down "config.h"
	- #define _ERRORCHECK_
	- choose "Bring Up To Date" from the Project menu
	- open your own project
	- choose "Make", then click "Use Disk", and then press Return

	The stars do work on a Mac II, but only in 1-bit mode. This is
because (for speed) the code writes directly to the window's portBits.
This doesn't quite work in multi-bit bitmaps...
