## 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.

Table 11-4 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) 1 | 44
| CHARACTER*len | MAX(7, 3*len)
L, G | LOGICAL(1), LOGICAL(2) LOGICAL(4), LOGICAL(8) | 2
F, E, EN, 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) 1 | 42 d: 33 e: 3
A2, 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) 1 | 16
| CHARACTER*len | len
1 VMS, U*X 2 The default is the actual length of the corresponding I/O list item.
