# 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 the following table:

Default Widths for Data Edit Descriptors
Edit Descriptor | Data Type of I/O List Item | w
--- | --- | ---
I, B, O, Z, G | BYTE | 7
| INTEGER(1), LOGICAL(1) | 7
| INTEGER(2), LOGICAL(2) | 7
| INTEGER(4), LOGICAL(4) | 12
| INTEGER(8), LOGICAL(8) | 23
O, Z | REAL(4) | 12
| REAL(8) | 23
| REAL(16) | 44
| CHARACTER*len | MAX(7, 3*len)
L, G | LOGICAL(1), LOGICAL(2), LOGICAL(4), LOGICAL(8) | 2
F, E, ES, G, D | REAL(4), COMPLEX(4) | 15 d: 7 e: 2
| REAL(8), COMPLEX(8) | 25 d: 16 e: 2
| REAL(16), COMPLEX(16) | 42 d: 33 e: 3
EN | REAL(4), COMPLEX(4) | 15 d: 6 e: 2
| REAL(8), COMPLEX(8) | 25 d: 16 e: 2
| REAL(16), COMPLEX(16) | 42 d: 32 e: 3
A1, G | LOGICAL(1) | 1
| LOGICAL(2), INTEGER(2) | 2
| LOGICAL(4), INTEGER(4) | 4
| LOGICAL(8), INTEGER(8) | 8
| REAL(4), COMPLEX(4) | 4
| REAL(8), COMPLEX(8) | 8
| REAL(16), COMPLEX(16) | 16
| CHARACTER*len | len
1 The default is the actual length of the corresponding I/O list item.
