+

+
+ When CCL program gives this nested structure of map to this command:
+ ((MAP-ID11
+ MAP-ID12
+ (MAP-ID121 MAP-ID122 MAP-ID123)
+ MAP-ID13)
+ (MAP-ID21
+ (MAP-ID211 (MAP-ID2111) MAP-ID212)

+ CCL_MapMultiple (CCL code of this command)
+ 16 (total number of MAPs and SEPARATORs)
+ -7 (1st SEPARATOR)
+ MAP-ID11
+ MAP-ID12
+ -3 (2nd SEPARATOR)
+ MAP-ID121
+ MAP-ID122

+ -4 (4th SEPARATOR)
+ MAP-ID211
+ -1 (5th SEPARATOR)
+ MAP_ID2111
+ MAP-ID212
+ MAP-ID22
+
+ A value of each SEPARATOR follows this rule:
+ MAP-SET := SEPARATOR [(MAP-ID | MAP-SET)]+
+ SEPARATOR := -(number of MAP-IDs and SEPARATORs in the MAP-SET)
+
+ (*)....Nest level of MAP-SET must not be over than MAX_MAP_SET_LEVEL.
+
+ When some map fails to map (i.e. it doesn't have a value for
+ reg[rrr]), the mapping is treated as identity.
+
+ The mapping is iterated for all maps in each map set (set of maps
+ separated by SEPARATOR) except in the case that lambda is
+ encountered. More precisely, the mapping proceeds as below:
+
+ At first, VAL0 is set to reg[rrr], and it is translated by the
+ first map to VAL1. Then, VAL1 is translated by the next map to
+ VAL2. This mapping is iterated until the last map is used. The
+ result of the mapping is the last value of VAL?. When the mapping
+ process reached to the end of the map set, it moves to the next
+ map set. If the next does not exit, the mapping process terminates,
+ and regard the last value as a result.
+
+ But, when VALm is mapped to VALn and VALn is not a number, the
+ mapping proceeds as follows:
+
+ If VALn is nil, the lastest map is ignored and the mapping of VALm
+ proceeds to the next map.
+
+ In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm
+ proceeds to the next map.
+
+ If VALn is lambda, move to the next map set like reaching to the
+ end of the current map set.
+
+ If VALn is a symbol, call the CCL program refered by it.
+ Then, use reg[rrr] as a mapped value except for -1, -2 and -3.
+ Such special values are regarded as nil, t, and lambda respectively.
+
+ Each map is a Lisp vector of the following format (a) or (b):
+ (a)......[STARTPOINT VAL1 VAL2 ...]
+ (b)......[t VAL STARTPOINT ENDPOINT],
+ where
+ STARTPOINT is an offset to be used for indexing a map,
+ ENDPOINT is a maximum index number of a map,
+ VAL and VALn is a number, nil, t, or lambda.
+
+ Valid index range of a map of type (a) is:
+ STARTPOINT <= index < STARTPOINT + map_size - 1
+ Valid index range of a map of type (b) is:
+ STARTPOINT <= index < ENDPOINT */

+CCL-PROGRAM is a symbol registered by register-ccl-program,

Read buffer is set to STRING, and write buffer is allocated automatically.

STATUS is a vector of [R0 R1 ... R7 IC], where
R0..R7 are initial values of corresponding registers,
IC is the instruction counter specifying from where to start the program.
If R0..R7 are nil, they are initialized to 0.
If IC is nil, it is initialized to head of the CCL program.
