VMS Help CC, Messages, NONOCTAL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Message        An octal constant contains non-octal digits.

 Description    An octal constant contains a non-octal digit.  The
                compiler will convert this non-octal digit to its
                corresponding octal value and use that value instead.
                For example, 0190 will be converted to 0210 (decimal
                136) as the non-octal digit 9 is converted to the
                octal 11.

 User Action    Correct the octal constant to use only octal digits.
