The Question is:
Is there a NetWork DDE Developers Kit for OpenVMS VAX ?????
The Answer is :
The OpenVMS Wizard is not certain of your use of DDE, and will
assume this is a request for the Microsoft Windows Dynamic Data
Exchange (DDE) protocol.
Both XML and COM are available for OpenVMS, and various packages
offer ODBC and JDBC (please see the FAQ), which may suffice.
The BEA ObjectBroker CORBA has (or had) offered DDE support, as
well -- please check the software application catalog referenced
in the OpenVMS FAQ.
