From: Steven Lerman <lerman@ATHENA.MIT.EDU>
System name:		m1-238-1
Type and version:	CVAXSTAR 6.4R
Display type:		SM

What were you trying to do?
	take log of 0

What's wrong:
	taking log of 0 in xcalc produces an illegal instruction
error. Program exits. This has been true since the very first version
of xcalc was made available.

What should have happened:
	xcalc should emulate real calculators. Something of the form
ERR should be displayed in place of the current value on the "LCD"
display. 

Please describe any relevant documentation references:
