DDE Functions in a 16-Bit Environment

This appendix describes DDE functions in 16-bit mode. This is useful information when you are migrating from 16-bit to 32-bit mode.

PC/3270 Windows mode and PC400 provide a dynamic data exchange (DDE) interface that allows applications to exchange data. The exchange of data between two Windows applications can be thought of as a conversation between a client and a server. The client initiates DDE conversations. The server in turn responds to the client. Personal Communications is a DDE server for the open sessions that Personal Communications is managing. For more information about DDE, refer to Microsoft Windows Software Development Kit Guide to Programming.
