- -1 (5th SEPARATER)
- TABLE_ID2111
- TABLE-ID212
- TABLE-ID22
-
- A value of each SEPARATER follows this rule:
- TABLE-SET := SEPARATOR [(TABLE-ID | TABLE-SET)]+
- SEPARATOR := -(number of TABLE-IDs and SEPARATORs in the TABLE-SET)
-
- (*)....Nest level of TABLE-SET must not be over than MAX_TABLE_SET_LEVEL.
-
- When some table fails to translate (i.e. it doesn't have a value
- for reg[rrr]), the translation is treated as identity.
-
- The translation is iterated for all tables in each table set (set
- of tables separators by a SEPARATOR) except the case that lambda is
- encountered (see below).
-
- Each table is a Lisp vector of the following format (a) or (b):
+ CCL_MapMultiple (CCL code of this command)
+ 16 (total number of MAPs and SEPARATORs)
+ -7 (1st SEPARATOR)
+ MAP-ID11

+ -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?.
+
+ But, when VALm is mapped to VALn and VALn is not a number, the
+ mapping proceed as below:
+
+ If VALn is nil, the lastest map is ignored and the mapping of VALm
+ proceed to the next map.
+
+ In VALn is t, VALm is reverted to reg[rrr] and the mapping of VALm
+ proceed to the next map.
+
+ If VALn is lambda, the whole mapping process terminates, and VALm
+ is the result of this mapping.
+
+ 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 table,
- ENDPOINT is a maxmum index number of a table,
+ 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 table of type (a) is:
- STARTPOINT <= index < STARTPOINT + table_size - 1
- Valid index range of a table of type (b) is:
- STARTPOINT <= index < ENDPOINT
+ 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 */
- If VALn is nil, the table is ignored and translation proceed to the
- next table.
- In VALn is t, reg[rrr] is reverted to the original value and
- translation proceed to the next table.
- If VALn is lambda, translation in the current TABLE-SET finishes
- and proceed to the upper level TABLE-SET. */
