515 -3 (2nd SEPARATOR)

526 MAP-ID212
|
|
|
527 MAP-ID22
|
|
|
528
|
|
|
529 A value of each SEPARATOR follows this rule:
|
|
|
530 MAP-SET := SEPARATOR [(MAP-ID | MAP-SET)]+
|
|
|
531 SEPARATOR := -(number of MAP-IDs and SEPARATORs in the MAP-SET)
|
|
|
532
|
|
|
533 (*)....Nest level of MAP-SET must not be over than MAX_MAP_SET_LEVEL.
|
|
|
534
|
|
|
535 When some map fails to map (i.e. it doesn't have a value for
|
|
|
536 reg[rrr]), the mapping is treated as identity.
|
|
|
537
|
|
|
538 The mapping is iterated for all maps in each map set (set of maps
|
|
|
539 separated by SEPARATOR) except in the case that lambda is
|
|
|
540 encountered. More precisely, the mapping proceeds as below:
|
|
|
541
|
|
|
542 At first, VAL0 is set to reg[rrr], and it is translated by the
|
|
|
543 first map to VAL1. Then, VAL1 is translated by the next map to
|
|
|
544 VAL2. This mapping is iterated until the last map is used. The
|
|
444
|
545 result of the mapping is the last value of VAL?. When the mapping
|
|
|
546 process reached to the end of the map set, it moves to the next
|
|
|
547 map set. If the next does not exit, the mapping process terminates,
|
|
|
548 and regard the last value as a result.
|
|
428
|
549
|
|
|
550 But, when VALm is mapped to VALn and VALn is not a number, the
|
|
444
|
551 mapping proceeds as follows:
|
|
428
|
552
|
|
|
553 If VALn is nil, the lastest map is ignored and the mapping of VALm
|
|
444
|
554 proceeds to the next map.
|
|
428
|
555
|
|
|
556 In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm
|
|
444
|
557 proceeds to the next map.
|
|
428
|
558
|
|
444
|
559 If VALn is lambda, move to the next map set like reaching to the
|
|
|
560 end of the current map set.
|
|
|
561
|
|
|
562 If VALn is a symbol, call the CCL program refered by it.
|
|
|
563 Then, use reg[rrr] as a mapped value except for -1, -2 and -3.
|
|
|
564 Such special values are regarded as nil, t, and lambda respectively.
|
|
428
|
565
|
|
|
566 Each map is a Lisp vector of the following format (a) or (b):
|
|
|
567 (a)......[STARTPOINT VAL1 VAL2 ...]
|
|
|
568 (b)......[t VAL STARTPOINT ENDPOINT],
|
|
|
569 where
|
|
|
570 STARTPOINT is an offset to be used for indexing a map,
|
|
|
571 ENDPOINT is a maximum index number of a map,
|
|
442
|
572 VAL and VALn is a number, nil, t, or lambda.
|
|
428
|
573
|
|
|
574 Valid index range of a map of type (a) is:
|
|
|
575 STARTPOINT <= index < STARTPOINT + map_size - 1
|
|
|
576 Valid index range of a map of type (b) is:
|
|

577 STARTPOINT <= index < ENDPOINT */
