Makes a dynamic invoke asynchronously. That is, the INVOKE( ) method with ASYNCHRONOUS set to TRUE does dynamically what the RUN statement with the ASYNCHRONOUS option does statically.
Data type: LOGICAL
Access: Readable/Writable
Applies to: Call object handle
If ASYNCHRONOUS is TRUE, when the dynamic invoke returns successfully, it sets the ASYNC-REQUEST-HANDLE attribute to indicate an asynchronous-request object that provides information on this particular asynchronous request.
