IsReference: Boolean;
The IsReference property determines whether the coordinate is passed using the link.
If the property is set to True, not the value by this coordinate, but the link to the coordinate, described by the ICalculatedCubeInstanceCoord interface, is passed on calculating the formula. The property is set to False by default, actual value by this coordinate is passed to formulas. Setting the property to True is equivalent to setting the @ character before coordinate in the formula editor of calculated cube.
Executing the example requires a calculated cube with the Calc_Cube identifier, the cube has two dimensions. Also, a unit with the Calc_Functions identifier should be present, which implements calculated cube functions. There is the Test function among the others, which signature has a single parameter with the ICalculatedCubeInstanceCoord type. Also, add links to the Cubes, Matrix and Metabase system assemblies.

On executing the example the following formula is set by the specified source cube coordinate: the applied function is called, to which the cube coordinate is passed by the link.
