865 * The "TYPE" routine below is used to map them back to characters when
866 * necessary. The above mappings are required so that certain special
867 * characters are known to fit in 6 bits and/or can be easily spotted.
868 * Array elements beyond the end of the line should be filled with 0,

872 * separate numbers, that character should also translate to 0.
874 * This procedure may use the map1,map2 arrays to maintain static data for
875 * the mapping. MAP2(1) is set to 0 when the program starts
876 * and is not changed thereafter unless the routines on this page choose
