 the beginning "'" and ending "'[BHO]" strings,
 as lexer cannot remove them as it was done in the ANTLR V2 Parser.
 Do NOT use [BHO]STRING(MATCH)? in any rule, use these instead.

 Rule pr_CString is for CSTRING to remove the beginning and ending '"' characters,
 as lexer cannot remove them as it was done in the ANTLR V2 Parser.
 Do NOT use CSTRING in any rule, use this instead.

      and also at the last (highest precedence) level, if there is no match to other operators.
      If any of these unary operators was matched in the last rule, control must jump back to the rule of its precedence level ( NOT E4, NOT4B E11 ).
      Example case:
        not4b a & not4b b  <=>  not4b ( a & ( not4b b ) )
72
        1st not4b matches in rule E11, but the 2nd not4b matches in rule P.
