open-port

Arguments: client-port

Connects with the DDE server application named by the port-application of the specified client-port, for the topic named by the port-topic of the client-port. This must be done for any client-port before the communication with the DDE server can commence.

To change the topic or application of a client-port, it must first be closed with close-port and then reopened with open-port (after changing the port-topic or port-application of the port). It may be more straightforward, however, to use a separate client-port object for each topic of each application that is used.

See dde.htm for information about DDE support.
