Appendix C. Programming with GDDM under TSO

GDDM V3R2 Base Application Programming Guide
SC33-0867-01

This appendix describes the use of GDDM under the TSO operating system. It covers these topics:

Link-editing a GDDM application program
Data sets and file processing
Display terminal processing
Using APL terminals
Using GDDM under TSO or MVS batch
An example of JCL for link editing GDDM applications.

Application programs using GDDM have no particular restrictions or requirements. However, if a PL/I program uses the GDDM-supplied declarations it must have access to the library on which they are held. It must also be link-edited with one of the interface modules as described below.

Terminal users should be aware of the GDDM usage of PA1, PA2, and the CLEAR keys. Also, there is a possibility of unexpected terminal responses after a GDDM application program has ended abnormally. These matters are described under "Display terminal processing" in topic C.3.
