Add visual presentations to your host applications with GDDM

IBM® Graphical Data Display Manager (GDDM) is a family of programs that provides presentation services in IBM host data processing applications. These services are comprised of a set of functions for showing data on IBM display terminals and other devices. GDDM will send the data to a wide range of devices besides displays, including printers, plotters and host-attached personal computers. GDDM also accepts input, reading alphanumeric data from a keyboard, graphic data from a tablet or mouse, and image data from a scanner.


Enhance host applications

Create graphics, images and alphanumeric text for display, or print for a range of supported output devices. Read device input and divide screens into independent windows.

Simplify with APIs

Take advantage of a set of user interfaces in the form of APIs to create graphics and draw charts, and enable visual data to be input to and output from application programs and GDDM utilities.

Connect GDDM quickly

Avoid writing your own applications to support GDDM. Many IBM and other software packages take advantage of GDDM — you may even find that you are already using one of them.
