PURPOSE: A method for compressing 2-byte character data is provided to save a storage space by compressing a 2-byte text message and storing the compressed data. CONSTITUTION: The maximum number of character strings, the number of code words and initial dictionary entry number are initialized, characters with high frequency are stored in a basic dictionary table, and a variable indicating a next codeword to be registered is initialized(S101). An additional compression-available codeword is stored in a supplementary dictionary table including the basic dictionary table, and the variable indicating the next codeword to be registered is re-initialized(S102). Message data is sequentially inputted and if the inputted data is included in the compression-available codeword, a corresponding code is searched from the dictionary table and outputted(S103). It is checked whether the corresponding code is in the dictionary(S104). It is determined whether it is the end of the data(S105). If so, a flushing process is performed(S106).
