This topic briefly describes the interface between z/OS® XL C and applications generated through the Cross System Product/Application Development (CSP/AD) and the Cross System Product/Application Execution (CSP/AE) Version 3 Release 2 Modification 2 or later. CSP refers to both CSP/AD and CSP/AE.
CSP/AD is an interactive application generator that provides methods for interactively defining, testing, and generating application programs. It can aid in improving productivity in application development.
CSP/AE takes the generated program and executes it in a production environment.
