Syntax Element Description
operand1
Object Handle:

operand1 must be defined as an object handle (HANDLE OF OBJECT). The object handle is filled when the object is successfully created. When not successfully returned, operand1 contains the value NULL-HANDLE.

OF CLASS operand2
Class-Name:

operand2 is the name of the class of which the object is to be created. For classes that are not registered as DCOM classes, it must contain the class name defined in the DEFINE CLASS statement. For classes that are registered as DCOM classes, it must contain either the ProgID of the class or the class GUID. For Natural classes that are registered as DCOM classes, the ProgID corresponds to the class name specified in the DEFINE CLASS statement.
