502 (MAP-ID211 (MAP-ID2111) MAP-ID212)
504 the compiled CCL codes has this sequence:
505 CCL_MapMultiple (CCL code of this command)
506 16 (total number of MAPs and SEPARATORs)
524 A value of each SEPARATOR follows this rule:
525 MAP-SET := SEPARATOR [(MAP-ID | MAP-SET)]+
526 SEPARATOR := -(number of MAP-IDs and SEPARATORs in the MAP-SET)
528 (*)....Nest level of MAP-SET must not be over than MAX_MAP_SET_LEVEL.
530 When some map fails to map (i.e. it doesn't have a value for
531 reg[rrr]), the mapping is treated as identity.
533 The mapping is iterated for all maps in each map set (set of maps
534 separated by SEPARATOR) except in the case that lambda is
535 encountered. More precisely, the mapping proceeds as below:
537 At first, VAL0 is set to reg[rrr], and it is translated by the
538 first map to VAL1. Then, VAL1 is translated by the next map to
539 VAL2. This mapping is iterated until the last map is used. The
540 result of the mapping is the last value of VAL?.
542 But, when VALm is mapped to VALn and VALn is not a number, the
543 mapping proceed as below:
545 If VALn is nil, the lastest map is ignored and the mapping of VALm
546 proceed to the next map.
548 In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm
549 proceed to the next map.
551 If VALn is lambda, the whole mapping process terminates, and VALm
552 is the result of this mapping.
554 Each map is a Lisp vector of the following format (a) or (b):
555 (a)......[STARTPOINT VAL1 VAL2 ...]
556 (b)......[t VAL STARTPOINT ENDPOINT],
558 STARTPOINT is an offset to be used for indexing a map,
559 ENDPOINT is a maximum index number of a map,
560 VAL and VALn is a number, nil, t, or lambda.
562 Valid index range of a map of type (a) is:
563 STARTPOINT <= index < STARTPOINT + map_size - 1
564 Valid index range of a map of type (b) is:
565 STARTPOINT <= index < ENDPOINT */
