SAS Companion for the OS/2 Environment

Overview of Dynamic Data Exchange

Dynamic Data Exchange (DDE) is a method of dynamically exchanging information between OS/2 applications. DDE uses a client/server relationship to enable a client application to request information from a server application. The SAS System is always the client. In this role, the SAS System requests data from server applications, sends data to server applications, or sends commands to server applications.

You can use DDE with the DATA step, the SAS macro facility, SAS/AF applications, or any other portion of the SAS System that requests and generates data. DDE has many potential uses, one of which is to acquire data from an OS/2 spreadsheet or database application.
