When state A is active, receive messageM. If the message has a data value equal to 3, discard the message. Then, when state B is active, check that the message M is still valid. If the message is valid and has a data value equal to 6, discard the message.

In state A:

during: if receive(M) == true if M.data == 3 discard(M); end end

In state B:

during: if isvalid(M) == true if M.data == 6 discard(M); end end
