| -**    YYCODETYPE         is the data type used for storing terminal
 | 
| -**                       and nonterminal numbers.  "unsigned char" is
 |

 | 
| -**                       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

 | 
| -** 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_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
