Device characteristics tokens

GDDM V3R2 Base Application Programming Reference

This topic describes the device characteristic tokens (usually called device tokens) supplied by GDDM. Many Input/Output tasks in GDDM can be done without using device tokens at all; however, there are some instances where they should be used. For example:

Under IMS/VS, to define the database that links the characteristics of terminals with logical terminal names, and so determine the type of data stream that GDDM sends.
To specify some special types of device, such as AFPDS printers, in a DSOPEN call.
To override the information obtained by GDDM about a particular device so that device information is taken from the token rather than from the device itself, which is the usual source.

Notes:

1. The paper sizes quoted in this topic generally refer to the usable area, not the actual sheet size.

2. Tokens for some obsolete devices have been omitted from the tables in this topic. These tokens are still available in the ADMLSYSn modules.
