Hi Henrik,
> One final question, how did you define the rd1> mechanism?
In the mentioned case, I used the followin method in the +Agent class
(dm rd1> (Sock)
(when (assoc Sock (: socks))
(rot (: socks) (index @ (: socks)))
(ext (: ext)
(or
(in Sock (rd))
(nil
(close Sock)
(pop (:: socks)) ) ) ) ) )
This looks a little complicated, as each agent maintains a list of open
sockets (in 'socks'). But if you omit the 'socks' management, it is
basically just
(ext (: ext) (in Sock (rd)))
followed by 'close' if the remote side closed the connection.

This should not be the case. It depends on what the other side sends. If
it sends a list, you'll get the whole list. In the examples we
discussed, however, the query results were sent one by one.

Yes, analog to 'read', 'line', 'char' etc.

Could it be that remote sends the result of 'collect'? This would be the
whole list then.
