Webreal, dimension(:) :: a a = a + 1. end subroutine incb Explanation The subroutine incb uses a Fortran 90 style assumed shape array (containing dimension(:)). Such routines must either be in a module, or have an explicit interface wherever they are used. In this example, neither one was true. character :: a (5,5)*4 character (len=2), dimension (2) :: b (5,5)*4 ! Shape and length overridden. The form of specification using * is unique to character lengths (for functions and variables). Even non-character objects with length type parameters cannot use this syntax.
