yes,  I have found the problem.....    as it turns out,  there is a 
bug in lightspeed,  but not in the appletalk code.  Here is something 
similar to what was happening.

before entering thi code block,  the variable atpsocket equaled 200.

with myABRecord^^ do
begin
...
...
...
nbpAddress.asocket:=atpsocket;
...
...
...
end;

async:=true;
anOSErr:=NBPRegister(myABrecord,async);

the problem is with the use of with in lightspeed.
any normal rational human would assume that the value of myABRecord^^.nbpAddress
would be that of atpsocket after exiting the WITH block.  The assignment
above gave me a value of one however.  

I fixed thi by doing the assigment outside of the WITH block and all is
now well.  I am now on my way to bigger and better bugs.  Thanks much
for the reply.
