Dynamic Data Exchange (DDE) was a precursor to Microsoft's OLE
automation. DDE allows Windows applications to exchange data with one another.
TN3270 Plus DDE support allows you to write applications that send commands to,
and receive data from TN3270 Plus. Your application becomes the terminal
It is also possible to use the DDE commands available in the
TN3270 Plus scripting language to send data to DDE enabled
applications. For example, we have a user that wrote a TN3270 Plus
script that creates a monthly sales summary in a Microsoft Excel
spreadsheet. The TN3270 Plus script opens Microsoft Excel, uses DDE
to create a spreadsheet, uses screen scraping to gather information
from the mainframe computer and then uses DDE to move the data into
the Microsoft Excel spreadsheet. The result is spreadsheet with a
summary of monthly sales. A tedious, time consuming, error-prone data
entry task is automated into a single TN3270 Plus script.
