Descriptors and exit routines
Using descriptors and exit routines, you can assign characteristics to ETO dynamic terminals and assign user structures to be associated with those terminals.
A descriptor provides the basic information for the dynamic terminal.
An exit routine completes or changes this information. Two methods
of using descriptors and exit routines are:
- You can use many descriptors and code little or no processing logic in exit routines.
- You can use few descriptors and code exit routines to perform much of the processing.
