IBM PC divide bug revisited
Having access to an IBM PC, I couldn't resist trying to make the 
.1/10 giving .001 bug happen.  After many tries, I discovered that
as long as the division is done with variables, the result is ok. 
To successfully cause the "bug", I had to do the division using
double precision literals (print .1#/10#).  Unfortunately, I don't
think the bug is in the output routine as was earlier suspected.
The following program also fails!!
   c#=.1#/10#
   print c#
Maybe IBM will handle this the way they sometimes "fix" bugs on their
large systems... They'll change the manual and call it a "feature".

Oh yes, one other thing.  Did you know that .1#/100# == .1#/1000#?
They both yield .0001.
