A data descriptor must be provided for each data item present (or implied) in a data transfer list. Real, double precision, and complex items may use any of the E, F, or G descriptors but in all other cases the data type must match. Two floating-point descriptors are needed for each complex value.
Data type | Data descriptors |
Integer | Iw, Iw.m |
Real, Double Precision, or Complex | Ew.d, Ew.dEe, Fw.d, Gw.d, Gw.dEe |
Logical | Lw |
Character | A, Aw |
The letters w, m, d, and e used with these data descriptors represent unsigned integer constants; w and e must be greater than zero.
w | is the total field width. |
m | is the minimum number of digits produced on output. |
d | is the number of digits after the decimal point. |
e | is the number of digits used for the exponent. |
