Implementing the Autoinstall Exit Program

To implement autoinstall in a region you can use the supplied autoinstall exit DFHZATDX or you can specify your own autoinstall control program (ACP).

To use your own ACP you must:

1. Write an Autoinstall Control Program (ACP).

   The interface to ACP is fully defined in the section Auto Control Program Call Interface. Put the executable file for the program on the program path. The Autoinstall Processing section describes the flow of information between the ACP and a CICS Option region.

2. Enter the ACP program name in the Auto Install Exit field in the SIT.

   Information on updating the SIT is detailed in the section CICS SIT Details. You should be aware that the autoinstall exit interface is designed to be an ASCII interface. The autoinstall exit you specify in the Auto Install Exit field in the SIT must be a program compiled with the CHARSET(ASCII) Compiler directive.

3. Define one or more terminal models from which the ACP can select (see the section Defining Terminal Models)
