X + or -
X A sign character must immediately precede both the mantissa and the
X exponent.
X A + sign indicates that a positive sign will be used in the output to
X represent positive values and that a negative sign will represent
X negative values.
X A - sign indicates that a blank will be used in the output to
X represent positive values and that a negative sign will represent
X negative values.
X Each sign position occupies one byte of storage.
X mantissa
X The mantissa can contain the symbols:
X 9 . V
X An actual decimal point can be represented with a period (.) while an
X assumed decimal point is represented by a V.
X Either an actual or an assumed decimal point must be present in the
X mantissa; the decimal point can be leading, embedded, or trailing.
X The mantissa can contain from 1 to 16 numeric characters.
X E
X Indicates the exponent.
X exponent
X The exponent must consist of the symbol 99.
X Other Clauses: The OCCURS, REDEFINES, RENAMES, and USAGE clauses may be
X associated with external floating-point items.
X The SIGN clause is accepted as documentation and has no effect on the
X representation of the sign.
X The SYNCHRONIZED clause is treated as documentation.
X The following clauses are invalid with external floating-point items:
- X BLANK WHEN ZERO
- X JUSTIFIED
