Boundary conditions for COMPLEX or VECTOR VARIABLES may be declared for the complex or vector variable directly, or for the individual components.

If C is a COMPLEX VARIABLE with components Cr and Ci, the following boundary condition declarations are equivalent:

VALUE(C) = Complex(a,b)
VALUE(Cr) = a    VALUE(Ci) = b

If V is a VECTOR VARIABLE with components Vx and Vy, the following boundary condition declarations are equivalent:

NATURAL(V) = Vector(a,b)
NATURAL(Vx) = a    NATURAL(Vy) = b

The component form allows the application of different boundary condition forms (VALUE or NATURAL) to the components, while the root variable form does not.
