Hi Darin,
Note to everyone:  While I'm here I'd like to thank everyone who helped out 
with my query.  All info has been read and appreciated.  :-)  (I don't want 
to clutter up the echo and I'd netmail everyone but my experience with 
inter-zone netmail is that it never seems to work the way I want it to.  )
Darin McBride was saying something to Michael McGavin about "passing by 
reference":
 MM>> void afunction(int *var1)
 MM>> {
 MM>> *var1=546;
 MM>> }
 MM>> void main()
 MM>> {
 MM>> int k;
 MM>> afunction(&k);
 MM>> }

Thanks for helping to clear this up.  It's been a great help.  :-)
One thing that still holds my interest is how the compiler handles it 
automatically.  Is the code generated for passing by reference going to work 
out the same as passing a pointer to an object and subsequently dereferencing 
that pointer?
All the best.
Mike.                                   email: zog@sans.vuw.ac.nz
