Notes —
- The only sign specification which may be used for an external decimal field is an overpunched + or - in the rightmost position of the field. A + and - may not appear in the character by itself.
- An edited field may have a character position reserved for the sign or may have the sign over the rightmost digit.
- Numeric external fields may contain leading blanks which are treated as leading zeros.
- Scientific decimal is the edited form of the floating point. The maximum fractional portion of a scientific decimal field is 16 digits.
