Type
Integer This is an integer point which contains the return value of the
point DDEInitiate() command.
String This contains the application that supports DDE as a DDE
server. Typically, this is the name of the applications' *.EXE
executable file without the filename extension. At runtime, the
server application must be open or a value cannot be returned
and an error is reported.
String This contains the name of the topic recognised by the server
application. Typically, a topic is a document within an
application. At runtime, the topic must be open or a value
cannot be returned and an error is reported.
The topic may be left empty, which enables documents to open
remotely prior to making a specified connection. The topic
name 'System' may be used to find out which other topics
within the server application are available. However, this is
dependant on the server application supporting this topic.
