 Meaning of Double Quote
 -----------------------
 
    `g77' treats double-quote (`"') as beginning an octal constant of
 `INTEGER(KIND=1)' type when the `-fvxt' option is specified.  The form
 of this octal constant is
 
      "OCTAL-DIGITS
 
 where OCTAL-DIGITS is a nonempty string of characters in the set
 `01234567'.
 
    For example, the `-fvxt' option permits this:
 
      PRINT *, "20
      END
 
 The above program would print the value `16'.
 
     Integer Type, for information on the preferred construct for
 integer constants specified using GNU Fortran's octal notation.
 
    (In the GNU Fortran language, the double-quote character (`"')
 delimits a character constant just as does apostrophe (`'').  There is
 no way to allow both constructs in the general case, since statements
 like `PRINT *,"2000 !comment?"' would be ambiguous.)
