Another point of common confusion wrt JZOS: "JZOS" is really two separate things:
- The "JZOS batch launcher", for starting the Java JVM conveniently in batch - The "JZOS Toolkit" class library, which has Java classes and native code for accessing z/OS services and facilities. For example: classes for doing dataset I/O. You don't have to use the launcher in order to use the JZOS Toolkit class library, and vice versa.
