1. A method in a radio messaging system for forming a current frame of data, while maintaining a correct transmission order for numbered messages, the method comprising the steps of:

  • selecting a candidate message from a message queue;

    testing whether an available space in the current frame of data is sufficient to accommodate the candidate message;

    testing whether the selected candidate message is a numbered message;

    recording in a predetermined memory location a skip indicator, in response to the candidate message being a numbered message and the available space in the current frame being insufficient;

    skipping the candidate message during the current frame even though available space is sufficient, when the skip indicator is recorded in the predetermined memory location and is applicable to the candidate message;

    adding the candidate message to the current frame of data, when the available space in the current frame is sufficient and the candidate message is a message not affected by the skip indicator; and

    repeating the selecting, testing, recording, skipping, and adding steps to form the current frame of data.
