B-Coder supports a complete set of DDE commands that can be issued by other Windows programs allowing them to completely take control over all B-Coder functions. When you initiate a DDE link to B-Coder use the DDE Application Name B-Coder and the DDE Topic SYSTEM. (No DDE Item is necessary). The following is a list of all DDE commands that can be issued to B-Coder.
