11.2.7 Default Widths for Data Edit Descriptors

If w (the field width) is omitted for the data edit descriptors, the system applies default values. For the real data edit descriptors, the system also applies default values for d (the number of characters to the right of the decimal point), and e (the number of characters in the exponent).

These defaults are based on the data type of the I/O list item, and are listed in Table 11-4.
