Hi Folks,                                             06/02/91

Thanks to all who responed to me for NIH Libraries. Those who wants
to know about how to get it, please call me at (914) 724-4192.

I was wondering lately have we changed name of this group to

C++ and American Waitresses ?? (just kidding)


I am trying to implement a smalltalk like feature called circular
relationship in C++. What I mean is as follows.

Class Employee has reference to say for example Class Payroll. i.e
a pointer to object of class payroll. Now Class payroll also has
a pointer to obbject of class Employee. Got it ? A has reference to B
and B has reference to A. How would I go on implementing this ?

I tried extern class B in class A def file and extern Class A in 
class B def file. But it gives me error as it could not lookup complete
method for incomplete type def.

Any help would be appreciated.

P.S. I have not yet used NIH library. The moment I do, I will post 
     my experience.
