** YYCODETYPE is the data type used for storing terminal

** used if there are fewer than 250 terminals
** and nonterminals. "int" is used otherwise.
** YYNOCODE is a number of type YYCODETYPE which corresponds
** to no legal terminal or nonterminal number. This
** number is used to fill in empty slots of the hash
** table.
** YYFALLBACK If defined, this indicates that one or more tokens
** have fall-back values which should be used if the
** original value of the token will not parse.
** YYACTIONTYPE is the data type used for storing terminal
** and nonterminal numbers. "unsigned char" is
** used if there are fewer than 250 rules and
** states combined. "int" is used otherwise.
** ParseTOKENTYPE is the data type used for minor tokens given
** directly to the parser from the tokenizer.
** YYMINORTYPE is the data type used for all minor tokens.
** This is typically a union of many types, one of
** which is ParseTOKENTYPE. The entry in the union
** for base tokens is called "yy0".
** YYSTACKDEPTH is the maximum depth of the parser's stack. If
** zero the stack is dynamically sized using realloc()
** ParseARG_SDECL A static variable declaration for the %extra_argument
** ParseARG_PDECL A parameter declaration for the %extra_argument
** ParseARG_STORE Code to store %extra_argument into yypParser
** ParseARG_FETCH Code to extract %extra_argument from yypParser
** YYNSTATE the combined number of states.
** YYNRULE the number of rules in the grammar
** YYERRORSYMBOL is the code number of the error symbol. If not

/* Next are the tables used to determine what action to take based on the
** current state and lookahead token. These tables are used to implement
** functions that take a state number and lookahead value and return an
** action integer.
**
** Suppose the action integer is N. Then the action is determined as
** follows
**
** 0 <= N < YYNSTATE Shift N. That is, push the lookahead
** token onto the stack and goto state N.
**
** YYNSTATE <= N < YYNSTATE+YYNRULE Reduce by rule N-YYNSTATE.
**
** N == YYNSTATE+YYNRULE A syntax error has occurred.
**
** N == YYNSTATE+YYNRULE+1 The parser accepts its input.
**
** N == YYNSTATE+YYNRULE+2 No such action. Denotes unused
** slots in the yy_action[] table.
**
** The action table is constructed as a single large table named yy_action[].
** Given state S and lookahead X, the action is computed as
**
** yy_action[ yy_shift_ofst[S] + X ]
**
** If the index value yy_shift_ofst[S]+X is out of range or if the value
** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X or if yy_shift_ofst[S]
** is equal to YY_SHIFT_USE_DFLT, it means that the action is not in the table
** and that yy_default[S] should be used instead.
**
** The formula above is for computing the action when the lookahead is
** a terminal symbol. If the lookahead is a non-terminal (as occurs after
** a reduce action) then the yy_reduce_ofst[] array is used in place of
** the yy_shift_ofst[] array and YY_REDUCE_USE_DFLT is used in place of
** YY_SHIFT_USE_DFLT.
**
** The following are the tables generated in this section:
**
** yy_action[] A single table containing all actions.
** yy_lookahead[] A table containing the lookahead for each entry in
** yy_action. Used to detect hash collisions.
** yy_shift_ofst[] For each state, the offset into yy_action for
** shifting terminals.
** yy_reduce_ofst[] For each state, the offset into yy_action for
** shifting non-terminals after a reduce.
** yy_default[] Default action for each state.
