| 507 | |
| 508 When CCL program gives this nested structure of map to this command: | |

| 513 (MAP-ID21 | |
| 514 (MAP-ID211 (MAP-ID2111) MAP-ID212) | |
| 515 MAP-ID22)), | |
| 444 | 516 the compiled CCL code has this sequence: |
| 428 | 517 CCL_MapMultiple (CCL code of this command) |
| 518 16 (total number of MAPs and SEPARATORs) | |
| 519 -7 (1st SEPARATOR) | |
| 520 MAP-ID11 | |
| 521 MAP-ID12 | |
| 522 -3 (2nd SEPARATOR) | |
| 523 MAP-ID121 | |
| 524 MAP-ID122 | |
| 525 MAP-ID123 | |
| 526 MAP-ID13 | |
| 527 -7 (3rd SEPARATOR) | |
| 528 MAP-ID21 | |
| 529 -4 (4th SEPARATOR) | |
| 530 MAP-ID211 | |
| 531 -1 (5th SEPARATOR) | |
| 532 MAP_ID2111 | |
| 533 MAP-ID212 | |
| 534 MAP-ID22 | |
| 535 | |
| 536 A value of each SEPARATOR follows this rule: | |
| 537 MAP-SET := SEPARATOR [(MAP-ID | MAP-SET)]+ | |
| 538 SEPARATOR := -(number of MAP-IDs and SEPARATORs in the MAP-SET) | |
| 539 | |
| 540 (*)....Nest level of MAP-SET must not be over than MAX_MAP_SET_LEVEL. | |
| 541 | |
| 542 When some map fails to map (i.e. it doesn't have a value for | |
| 543 reg[rrr]), the mapping is treated as identity. | |
| 544 | |
| 545 The mapping is iterated for all maps in each map set (set of maps | |
| 546 separated by SEPARATOR) except in the case that lambda is | |
| 547 encountered. More precisely, the mapping proceeds as below: | |
| 548 | |
| 549 At first, VAL0 is set to reg[rrr], and it is translated by the | |
| 550 first map to VAL1. Then, VAL1 is translated by the next map to | |
| 551 VAL2. This mapping is iterated until the last map is used. The | |
| 444 | 552 result of the mapping is the last value of VAL?. When the mapping |
| 553 process reached to the end of the map set, it moves to the next | |
| 554 map set. If the next does not exit, the mapping process terminates, | |
| 555 and regard the last value as a result. | |
| 428 | 556 |
| 557 But, when VALm is mapped to VALn and VALn is not a number, the | |
| 444 | 558 mapping proceeds as follows: |
| 428 | 559 |
| 560 If VALn is nil, the lastest map is ignored and the mapping of VALm | |
| 444 | 561 proceeds to the next map. |
| 428 | 562 |
| 563 In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm | |
| 444 | 564 proceeds to the next map. |
| 428 | 565 |
| 444 | 566 If VALn is lambda, move to the next map set like reaching to the |
| 567 end of the current map set. | |
| 568 | |
| 569 If VALn is a symbol, call the CCL program refered by it. | |
| 570 Then, use reg[rrr] as a mapped value except for -1, -2 and -3. | |
| 571 Such special values are regarded as nil, t, and lambda respectively. | |
| 428 | 572 |
| 573 Each map is a Lisp vector of the following format (a) or (b): | |
| 574 (a)......[STARTPOINT VAL1 VAL2 ...] | |
| 575 (b)......[t VAL STARTPOINT ENDPOINT], | |
| 576 where | |
| 577 STARTPOINT is an offset to be used for indexing a map, | |
| 578 ENDPOINT is a maximum index number of a map, | |
| 442 | 579 VAL and VALn is a number, nil, t, or lambda. |
| 428 | 580 |
| 581 Valid index range of a map of type (a) is: | |
| 582 STARTPOINT <= index < STARTPOINT + map_size - 1 | |
| 583 Valid index range of a map of type (b) is: | |
| 584 STARTPOINT <= index < ENDPOINT */ | |
