ASYNCHRONOUS attribute

Makes a dynamic invoke asynchronous. That is, the INVOKE( ) method with ASYNCHRONOUS set to TRUE does dynamically what the RUN statement with the ASYNCHRONOUS option does statically.

Note: If ASYNCHRONOUS is TRUE, the logic being invoked must reside on an AppServer.

Data type: LOGICAL

Access: Readable/Writable

Applies to: CALL object handle

Syntax

ASYNCHRONOUS [ = logical-expression ]

logical-expression

A LOGICAL expression which, if TRUE, makes the dynamic invoke asynchronous. The default is FALSE.

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.
