GNU Fortran allows old-style kind specifications in declarations. These look like:
TYPESPEC*size x,y,z
where TYPESPEC
is a basic type (INTEGER
, REAL
,
etc.), and where size
is a byte count corresponding to the
storage size of a valid kind for that type. (For COMPLEX
variables, size
is the total size of the real and imaginary
parts.) The statement then declares x
, y
and z
to
be of type TYPESPEC
with the appropriate kind. This is
equivalent to the standard-conforming declaration
TYPESPEC(k) x,y,z
where k
is equal to size
for most types, but is equal to
size/2
for the COMPLEX
type.
