Format Data Descriptors A, E, F, G, I, L

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.

Any data descriptor can be preceded by a repeat-count (also an unsigned integer), thus:
3F6.0 is equivalent to F6.0,F6.0,F6.0
This facility is particularly useful when handling arrays.
