------- Comment #4 from burnus at gcc dot gnu dot org 2008-08-25 20:39 -------
Note: Using
COMPLEX*16 X(1)
defines a rank-one array with a single argument. Accessing then
X(2)
is invalid according to the Fortran standard - there is no such element. (I
know that several old Fortran programs use such a wrong syntax both as actual
as well as as formal argument even though a complete array is meant.)
As Dominique wrote, one can use:
COMPLEX*16 X(*)
which is the correct syntax.
