TSO/VTAM exit routines

This topic contains information you need to write exit routines for TSO/VTAM. You can write routines to do the following:

Perform input and output editing that replaces or supplements IBM-supplied editing.
Perform attention handling that replaces IBM-supplied attention handling.
Provide support for terminals not supported by TSO/VTAM.
Note: To support terminals not supported by TSO/VTAM, write your own terminal input manager and terminal output manager, in addition to exit routines IKTGETXT, IKTINX2, IKTCASX1, and IKTINX1.
Verify that a specified terminal type can receive TSO/VTAM user messages in the language requested by the terminal user.

Note: TSO/VTAM exit routines are optional. However, if you do not write these exit routines, you will get unresolved external reference messages during link-editing of the load modules that call them. To determine whether you need any of the input and output editing exit routines, see the topics on the TPUT and TGET options in z/OS TSO/E Programming Services.
