	DDE - Direct Data Entry, Dynamic Data Exchange
		A DDE conversation is a two-way connection between two applications, used to transmit data by each program alternately.
		DDE is a form of interprocess communication implemented in multitasking operating systems such as Microsoft Windows and OS/2.
		An exchange of data in DDE is called a conversation and an application can participate simultaneously in multiple DDE conversations with any number of other applications.

	dynamic data exchange - Hutchinson encyclopedia article about dynamic data exchange
		In computing, a form of interprocess communication used in Microsoft Windows, providing exchange of commands and data between two applications.
		DDE was used principally to include live data from one application in another – for example, spreadsheet data in a word-processed report.
		DDE links between files rely on the files remaining in the same locations in the computer's directory.

	WinWedge - Sending Keystrokes Vs. Dynamic Data Exchange (DDE)
		For example, when reading data into a spreadsheet, a common requirement is to have successive readings from a device appear in a column in the spreadsheet.
		DDE on the other hand does not require the receiving application to have the input focus therefore all data transfers can occur in the background while you work with other programs in the foreground.
		One way to accomplish this is to have WinWedge issue a DDE Command after each input that causes the spreadsheet to run a macro that either requests the data or copies any linked DDE data into a column.

	Using Dynamic Data Exchange : DDE Examples
		In addition, DDE enables you to poll the data when the HOTLINK option is specified to determine whether data within the range that was specified have been changed.
		DDE also enables you to program when the DDE buffer is dumped during a DDE link.
		Normally, the data in the DDE buffer are transmitted when the DDE link is closed at the end of the DATA step.

	Dynamic Data Exchange with Other Applications
		Dynamic Data Exchange (DDE) allows a change in a source file to be immediately transmitted to a receiving (dependent) file, providing the application(s) running the files support DDE functionality, such as this software and Microsoft Excel.
		DDE is implemented using the Paste Link option from the Edit menu, which is only available when data has been copied to the clipboard.
		Data cannot be entered or copied into a range of a data set that is receiving information from a DDE link.

	Using Dynamic Data Exchange : Overview of Dynamic Data Exchange (Site not responding. Last check: 2007-11-02)
		DDE uses a client/server relationship to enable a client application to request information from a server application.
		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.

	Dynamic Data Exchange (Site not responding. Last check: 2007-11-02)
		As a client/server protocol, DDE enables data to be dynamically exchanged, and thus shared, between two applications running on the same machine.
		DDE is transaction-based because all communications between DDE client and server applications occur within the context of a DDE conversation.
		Before a data format is used by a DDE application, the application must ensure the data format has a unique identification by registering its name in the system atom table.

	Dynamic Data Exchange (DDE) and NetDDE FAQ
		DDE is ideal for allowing one program to monitor another, because neither program ever executes in the context of the other so they cannot interfere with each other.
		It informs the server of the data required by the client in a request transaction, the action to be taken by the server in an execute transaction or the data being passed to the server in a poke transaction.
		DDE is an asynchronous process, but is made to appear synchronous when the message sender chooses to suspend execution whilst waiting for a reply.

	Understanding Dynamic Data Exchange (DDE)
		Dynamic Data Exchange is a feature of Windows that allows two programs to share data or send commands directly to each other.
		The application that is the source of the data is called the "server" and the application that is receiving the data is called the "client".
		The types of DDE commands, if any, that a server program can accept will vary depending on the application and should be well documented in the application's user's manual along with the DDE Application Name and Topic required by client programs to establish the DDE link to the server’s command processor.

		Using the DDE functions, data can be entered into one or more columns in a.qdb file's Data Editor directly from another application.
		With a Paste Link set, as new data is entered into the source application (MS-Excel, in our example), the data is added to the receiving application in real time.
		The data cannot, however, be edited from the receiving application.

	What is DDE? - A Word Definition From the Webopedia Computer Dictionary
		DDE enables two running applications to share the same data.
		For example, DDE makes it possible to insert a spreadsheet chart into a document created with a word processor.
		Although the DDE mechanism is still used by many applications, it is being supplanted by OLE, which provides greater control over shared data.

		For example, when you change a form in your database program or a data item in a spreadsheet program, they can be set up to also change these forms or items anywhere they occur in other programs you may use.
		DDE is interprocess communication (IPC) that uses shared memory as a common exchange area and provides applications with a protocol or set of commands and message formats.
		DDE uses a client/server model in which the application requesting data is considered the client and the application providing data is considered the server.

	Dynamic Data Exchange (DDE) - Script Example (Site not responding. Last check: 2007-11-02)
		The process, in general, is that the DDE Client uses an INITIATE or ACCESS command to establish a DDE conversation with the DDE Server, and then uses commands supported by the DDE Server.
		Specifically, this script supports the ability of a DDE Client to send characters to the active host session, or to request the data displayed in the session window.
		If the DDE Client needed data from particular regions of the screen, but not the whole session, individual WHEN REQUESTS could be set up to serve those independent requests.

	Network Dynamic Data Exchange (Site not responding. Last check: 2007-11-02)
		Dynamic Data Exchange (DDE) client and server programs will automatically work over a network connection, without any code changes, as long as the two machines are configured properly and by having the client program reference the remote server's computer name instead of the local server's application name.
		Before trying to make two DDE programs communicate over a network, make them exchange data while both are running on the same computer to be sure you are successfully using DDE.
		PROGRAMMERS: To code DDE client/server applications, use the routines in the Dynamic Data Exchange Management Library (DDEML), as opposed to the harder-to-implement lower-level basic DDE routines the DDEML is built on.
