1. A two-way selective call receiving device for disabling a response to a previously stored message, comprising:

  • a receiver for receiving a message and an identifier associated with said message, said identifier falling within a limited set of possible identifiers that are reusable;

    a memory, coupled to the receiver, for storing the message and the identifier associated with said message;

    a controller, responsive to a received message having a given identifier, for searching said memory to determine if said memory has a previously stored message associated with an identifier that is the same as said given identifier, said controller preventing a response to said previously stored message from thereafter being transmitted if said controller determines that the previously stored message has been received with an identifier that is the same as said given identifier;

    a transmitter, coupled to the controller, for transmitting the response to the received message wherein said response is associated with said given identifier of the received message.
