DDE Control Centre """""""""""""""""" DDE Control Centre was originally written to experiment with DDE, and to determine what applications provided program control via DDE. The initial design simply "peeked" and "poked" the various settings provided by applications such as Window's Program Manager, Lotus 1-2-3 and Microsoft Access, but later developed to include a simplistic macro language. This allowed various DDE conversations to be pre-scripted using DDE, and then incorporated into final applications. Since then, the language has grown to encompass some of the more commonly required functions of inter-process communication including AppActivate, Maximize/Maximise, Minimize/Minimise, etc. If interest is sufficient, this language will be expanded to include variables, loops, and many of the features we have come to expect from standard application programming languages such as Visual Basic, Applications Edition.
