1. A computer-readable recording medium having therein a computer program for use in a variable length code, the program generating a code word table in which code words having code length according to occurrence probability of a plurality of source symbols are assigned for the source symbols, the code words being capable of being decoded both in forward and backward directions and being formed so that delimiters of the code words are capable of being identified by a predetermined weight of the code words, the code word table associating the code words with the inputted source symbols, the program outputting the code word corresponding to the inputted source symbol as coding data, comprising:

  • selecting the code word corresponding to the inputted source symbol from the code word table;

    assigning the selected code word to every synchronization interval; and

    inserting a stuffing code capable of being decoded in backward direction to set a code length corresponding to the synchronization interval when code length of the code word assigned to the synchronization interval is less than code length of the synchronization interval.
