Matthew says

<<OK, so if  do this

declare
   m1, m2 : slope;
begin
   if m1 = m2 then

and I'm using IEEE floating point types (I'm on a SUN box), can I assume
that the lines are parallel?
>>


This code is obviously erroneous as written, since m1 and m2 are 

not initialized.

Presumbaly there is unknown code to compute m1 and m2 missing here, and
of coruse the answer to the question depends on this code, and on the
problem requirements, and on the accuracy of the input information.
