Designing device-independent programs

GDDM V3R2 Base Application Programming Guide
SC33-0867-01

The information in this topic is aimed to help you write application programs that perform equally well on many different devices.

When you write a GDDM application program, you may have a very good idea of who the end users will be and even what kinds of terminal, workstation, printer, and plotter they use. It may be quite straightforward to write an application that functions perfectly with just those devices but the more specific your program is to one type of machine the less it is worth to you.

Programs that are written so that they are not specific to any one device or family of devices are of more use to more people and have a longer useful life span if they continue to function with new devices.
