Description

Implements all the methods that do not return values.

Implement DoProcedure to provide the implementation for method calls that do not return values. When the application invokes a Variant member function (Delphi) or calls the Variant's Exec method (C++), a call is automatically generated to DoProcedure.

The following table lists the parameters expected by this method.

Value	Meaning
V	The TVarData record from the Variant instance that was used to call the function.
Name	The name of the function being called.
Arguments	Dynamic array of TVarData records, where each record represents the value of an argument passed to the function.

DoProcedure returns True if it executes the method call, or False if it does not implement the specified procedure.
