Using DDE Functions

 

Although the Copy/Paste Link method of exchanging data is quite simple, advanced DDE applications can be constructed using DADiSP's built in DDE functions. The DDE functions are most often used when DADiSP acts as a DDE client.

 

The following table lists available DDE functions and actions:
