FNC_GetArrayNumDimensions takes an ARRAY handle as input and returns the number of dimensions defined for the ARRAY in the numDimensions output parameter.

You can use this function to retrieve the number of dimensions in an ARRAY type when this information is not known to the external routine. This also enables the UDF writer to write code so that it is dimension independent for any ARRAY types accessed in the routine.
