8146262a KH |
532 | MAP-SET := SEPARATOR [(MAP-ID | MAP-SET)]+ |
533 | SEPARATOR := -(number of MAP-IDs and SEPARATORs in the MAP-SET) | |
6ae21908 | 534 | |
8146262a | 535 | (*)....Nest level of MAP-SET must not be over than MAX_MAP_SET_LEVEL. |
6ae21908 | 536 | |
8146262a KH |
537 | When some map fails to map (i.e. it doesn't have a value for |
538 | reg[rrr]), the mapping is treated as identity. | |
6ae21908 | 539 | |
8146262a | 540 | The mapping is iterated for all maps in each map set (set of maps |
9b27b20d KH |
541 | separated by SEPARATOR) except in the case that lambda is |
542 | encountered. More precisely, the mapping proceeds as below: | |
543 | ||
544 | At first, VAL0 is set to reg[rrr], and it is translated by the | |
545 | first map to VAL1. Then, VAL1 is translated by the next map to | |
546 | VAL2. This mapping is iterated until the last map is used. The | |
54fa5bc1 KH |
547 | result of the mapping is the last value of VAL?. When the mapping |
548 | process reached to the end of the map set, it moves to the next | |
549 | map set. If the next does not exit, the mapping process terminates, | |
550 | and regard the last value as a result. | |
9b27b20d KH |
551 | |
552 | But, when VALm is mapped to VALn and VALn is not a number, the | |
553 | mapping proceed as below: | |
554 | ||
555 | If VALn is nil, the lastest map is ignored and the mapping of VALm | |
556 | proceed to the next map. | |
557 | ||
558 | In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm | |
559 | proceed to the next map. | |
560 | ||
54fa5bc1 KH |
561 | If VALn is lambda, move to the next map set like reaching to the |
562 | end of the current map set. | |
563 | ||
564 | If VALn is a symbol, call the CCL program refered by it. | |
565 | Then, use reg[rrr] as a mapped value except for -1, -2 and -3. | |
566 | Such special values are regarded as nil, t, and lambda respectively. | |
6ae21908 | 567 | |
8146262a | 568 | Each map is a Lisp vector of the following format (a) or (b): |
6ae21908 KH |
569 | (a)......[STARTPOINT VAL1 VAL2 ...] |
570 | (b)......[t VAL STARTPOINT ENDPOINT], | |
571 | where | |
8146262a | 572 | STARTPOINT is an offset to be used for indexing a map, |
9b27b20d | 573 | ENDPOINT is a maximum index number of a map, |
177c0ea7 | 574 | VAL and VALn is a number, nil, t, or lambda. |
6ae21908 | 575 | |
8146262a KH |
576 | Valid index range of a map of type (a) is: |
577 | STARTPOINT <= index < STARTPOINT + map_size - 1 | |
578 | Valid index range of a map of type (b) is: | |
