Old-style kind specifications (The GNU Fortran Compiler)

#### 5.1.1 Old-style kind specifications ¶

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 the kind parameter suitable for the intended precision. As kind parameters are implementation-dependent, use the `KIND`, `SELECTED_INT_KIND`, `SELECTED_LOGICAL_KIND` and `SELECTED_REAL_KIND` intrinsics to retrieve the correct value, for instance `REAL*8 x` can be replaced by:

    INTEGER, PARAMETER :: dbl = KIND(1.0d0)
    REAL(KIND=dbl) :: x
