This book introduces you to the Language Environment® architecture, a system of constructs and interfaces that provides a common runtime environment and runtime services for all Language Environment-conforming programming language products (those products that adhere to Language Environment's common interface). The book contains an overview of Language Environment, descriptions of Language Environment's full program model, and callable services. This is not a programming manual, but rather a conceptual introduction to Language Environment. Language Environment is offered on z/OS.

Language Environment Concepts Guide should be read by those who design systems installations and develop application programs. This high-level guide will show how best to plan for systems to support your enterprise.
