A reply can be executed in response to a SEND /RECY request without executing
the RECEIYE subfunction. This indicates that you do not want to receive the
message but may want to send a reply. A reply of zero length could be executed
simply to terminate the SEND /RECY request. The application of the REPLY
subfunction is a user decision. It must be used to terminate a SEND/RECY
request, however, unless the REJECT sub function is executed (See"REJECT: DIAGNOSE Code X'68' Subfunction Code X'OOll "'.) The reply is complete
when the source virtual machine receives the external interrupt response.
A REPLY subfunction cannot be executed in response to a SEND request (this is a
protocol violation).
