The ACLASS() function places the class name of an object and its ancestors into a variable one-dimensional array. The name of the object is specified in <object>. The name if the array is specified in <array>. If the array does not exist, it is created. If the array is smaller or larger than required, it is resized. The object class name is placed in the first element of the array, the class name of its immediate parent in the second element and so on through the class hierarchy.
The ACLASS() function returns the number of class names placed in the array. If the array cannot be created, the ACLASS() function will return 0.
