from section 13.5.9, F77 standard:

On output, the representation of a positive or zero internal value in
the field may be prefixed with a plus, as controlled by the S, SP, and
SS edit descriptors (13.5.6) or the processor. The representation of a
negative internal value in the field must be prefixed with a minus.
However, the processor must not produce a negative signed zero in a
formatted output record.
