Abstract
A processor (208) selects a candidate message (214) from a message queue (212), and tests (306) whether an available space (216) in the current frame of data is sufficient to accommodate the candidate message. The processor records (320, 420) a skip indicator (218, 220) into a predetermined memory location, in response to the candidate message being a numbered message and the available space in the current frame being insufficient. The processor skips (316) 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. The processor adds (332) 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. The processor continues (330) to select, test, record, skip, and add, as above, to form the current frame of data.
