I'd been puzzled for some time about a Level I Microware C
runtime error, #045, on my Coco.
The C manual lists only errors 41 thru 43, with 42 being
div-by-zero.
Since I suspected my program of doing just that,  I wrote
a quickie to deliberately /0, like:

	main() {
		short top, bot, q; /* for future 68K efficiency */
		top = 123;
		bot = 0;
		q = top / bot;
	}

and guess what, it gives out ERROR #045.

So 045 indeed means "divide by zero", in INT at least.
Perhaps the documented error 042 refers only to FLOAT /0;
someone want to test that? (I avoid floats, too sloooooowwwww).

I guess the Microware C library writers decided to be more specific
in error reporting (good!) after the manual was all typeset.
Now I wonder what 044 was assigned to ... ?

You think AT&T cares about CoCos, music, or Star Trek?
No?  Then, these opinions must be all mine!
