The program autoinstall facility uses model definitions, together with a user-replaceable program, to create explicit definitions for programs, mapsets, and partitionsets that need to be autoinstalled. CICS calls the user-replaceable program with a parameter list that gives the name of the appropriate model definition. On return from the program (depending on the return code), CICS creates a resource definition from information in the model and from parameters which the program returns.
For information about how to write the user-replaceable program, see CICS® Customization Guide.
