Node: Better List-directed I/O, Next: Default to Console I/O, Previous: Portable Unformatted Files, Up: Missing Features
Values output using list-directed I/O
(PRINT *, R, D)
should be written with a field width, precision, and so on
appropriate for the type (precision) of each value.
(Currently, no distinction is made between single-precision
and double-precision values
by libf2c.)
It is likely this item will require the libg77 project
to be undertaken.
In the meantime, use of formatted I/O is recommended.
While it might be of little consolation,
g77 does support FORMAT(F<WIDTH>.4), for example,
as long as WIDTH is defined as a named constant
(via PARAMETER).
That at least allows some compile-time specification
of the precision of a data type,
perhaps controlled by preprocessing directives.
