IBM Cross System Product (CSP) was a licensed program set for developing and running applications. Its two parts served different stages of that work: CSP/AD supported application development, while CSP/AE supported application execution.
What does IBM Cross System Product mean?
IBM’s glossary defines Cross System Product (CSP/AD and CSP/AE) as “A set of licensed programs designed to permit the user to develop and run applications using independently defined maps (display and printer formats), data items (records, working storage, files, and single items), and processes (logic).” In practical terms, an application was described through its display or printer layouts, the data it used, and its processing logic.
The name belongs to a specific IBM product context. It is not simply a general term for software that connects unrelated systems.

| Component | Role | Lifecycle work |
|---|---|---|
| CSP/AD | Application Development | Developing, testing, and generating applications |
| CSP/AE | Application Execution | Running applications, including production execution |
IBM’s glossary identifies these as the two parts of the CSP set. They are complementary roles, not competing products: one concerns creating and preparing applications, the other running them.

Which systems did IBM CSP run on?
IBM’s August 1983 product summary describes Development Management System/Cross-System Product (DMS/CSP) for SSX/VSE, as well as DMS/CSP offerings for CICS/VS, TSO, and VM/CMS. In that historical documentation, Definition facilities handled development, testing, and generation, while Execution offerings supported production use.
These environment names describe the product’s documented IBM context at the time. They do not establish compatibility with arbitrary non-IBM platforms, modern systems, or current software, nor do the cited historical materials establish present-day support or availability.

Why was it called “Cross System”?
CSP developed in the context of IBM’s efforts to support consistency across specified IBM environments. An IBM Systems Journal article published on September 1, 1988, discusses CSP’s evolution from a single-environment product to a multienvironment product and its relationship to IBM Systems Application Architecture (SAA).
IBM describes SAA as “a set of software interfaces, conventions, and protocols” that provided a framework for designing and developing applications with cross-system consistency. This helps explain the historical meaning of “cross system”: consistency among supported IBM environments, not automatic portability everywhere.
Quick Recap
What CSP does not mean
- It is not a generic name for modern system integration.
- Its historical multienvironment focus does not prove that CSP applications could run unchanged on any platform.
- The historical descriptions do not confirm that CSP is currently sold, supported, or compatible with contemporary systems.
