ABSTRACT:
A text compression technique used in a transmitter subsystem (126, 148) and a receiver subsystem (132, 158) for compressively encoding and decoding a text portion of a message by using tokens having at least two data symbol lengths. During encoding, a quantity of fill symbols are added to a sequence of secondary tokens, wherein the quantity of fill symbols is determined such that a total quantity of the data symbols in the sequence is equal to an integral multiple of the quantity of the data symbols having a first data symbol length. Delimiting characters such as spaces which precede a sequence of characters corresponding to a primary token are indicated by setting one data symbol in each primary token to a predetermined value. Sequences of capitalized characters are indicated by predetermined command tokens.
