/* The parser tables consist of these tables.
YYTRANSLATE = vector mapping yylex's token numbers into bison's
token numbers.
YYTNAME = vector of string-names indexed by bison token number.
YYTOKNUM = vector of yylex token numbers corresponding to entries
in YYTNAME.
YYRLINE = vector of line-numbers of all rules. For yydebug
printouts.
YYRHS = vector of items of all rules. This is exactly what RITEMS
contains. For yydebug and for semantic parser.
YYPRHS[R] = index in YYRHS of first item for rule R.
YYR1[R] = symbol number of symbol that rule R derives.
YYR2[R] = number of symbols composing right hand side of rule R.
YYSTOS[S] = the symbol number of the symbol that leads to state S.
YYDEFACT[S] = default rule to reduce with in state s, when YYTABLE
doesn't specify something else to do. Zero means the default is an
error.
YYDEFGOTO[I] = default state to go to after a reduction of a rule
that generates variable NTOKENS + I, except when YYTABLE specifies
something else to do.
YYPACT[S] = index in YYTABLE of the portion describing state S.
The lookahead token's type is used to index that portion to find
out what to do.
If the value in YYTABLE is positive, we shift the token and go to
that state.
If the value is negative, it is minus a rule number to reduce by.
If the value is zero, the default action from YYDEFACT[S] is used.
YYPGOTO[I] = the index in YYTABLE of the portion describing what to
do after reducing a rule that derives variable I + NTOKENS. This
portion is indexed by the parser state number, S, as of before the
text for this nonterminal was read. The value from YYTABLE is the
state to go to if the corresponding value in YYCHECK is S.
YYTABLE = a vector filled with portions for different uses, found
via YYPACT and YYPGOTO.
YYCHECK = a vector indexed in parallel with YYTABLE. It indicates,
in a roundabout way, the bounds of the portion you are trying to
examine.
Suppose that the portion of YYTABLE starts at index P and the index
to be examined within the portion is I. Then if YYCHECK[P+I] != I,
I is outside the bounds of what is actually allocated, and the
default (from YYDEFACT or YYDEFGOTO) should be used. Otherwise,
YYTABLE[P+I] should be used.
YYFINAL = the state number of the termination state. YYFLAG = most
negative short int. Used to flag ?? */
