        The CS parameter to specify a coordinate system is optional but might only be given if TYPE=VECTOR is used. By default, the standard Cartesian coordinate system (CS_0) is used.
        Only rectangular or cylindrical coordinate systems are allowed. The parameter <code class = "ph codeph">VEC_DIR</code> is interpreted as vector in this coordinate system.
        Its main purpose is to support movements in cylindrical coordinate systems.
