Reflection for IBM version 14.x or earlier
Reflection for UNIX and OpenVMS version 14.x or earlier
This technical note describes support for DDE (Dynamic Data Exchange) communication in Attachmate terminal emulation products.
DDE (Dynamic Data Exchange) is a type of communications between Microsoft Windows applications. It was more commonly used in the early 1990s before the existence of COM (Component Object Model).
DDE is supported in Reflection version 14.x and earlier (Windows-based emulation for IBM, HP, UNIX, and OpenVMS). This functionality can be disabled by group policy (see KB 7021691).
DDE is not supported by Extra! X-treme; InfoConnect products; KEA!; Reflection for the Web; Reflection Desktop, 2014, 2011, 2008, or 2007 products; or Verastream products.
It is strongly recommended that you update your applications to use a newer API instead of DDE. For more information on programming with Attachmate products, see KB 7022686.
