This section describes how to write a program to control the installation
of virtual terminals. Virtual terminals are used by:
- The External Presentation Interface (EPI) and terminal emulator functions
of the CICS® Clients products. For an introduction to the CICS Clients products,
and detailed information about CICS Transaction Server for z/OS® support for them, see the CICS Family: Communicating from CICS on System/390® manual.
- The CICS Link3270 bridge. In a bridged environment, these virtual terminals
replace the real 3270 that is the principal facility of a 3270 transaction.
They are known as bridge facilities.
Both the supplied autoinstall control programs, DFHZATDX and DFHZATDY,
provide function to install definitions of virtual terminals. You can therefore
base your customized control program on either DFHZATDX or DFHZATDY.
The section is divided into the following sections:
- How Client virtual terminals are autoinstalled
- The autoinstall control program at INSTALL
- The autoinstall control program at DELETE
- Default actions of the sample programs.
