Compiler and Library for REXX on zSeries

The architecture of the Compiler and Library for REXX on zSeries comprises several key components that work together to compile and execute REXX programs on z/OS and z/VM. The core components include the REXX compiler, the runtime library, and the load module binder. The REXX compiler translates REXX source code into either an intermediate representation or directly into load modules.

The runtime library provides the execution environment for interpreted REXX code and supports the execution of compiled load modules. The load module binder links compiled REXX code with other system components. These components communicate through a well-defined process.

The compiler processes the REXX source code and generates either an interpreted format or a load module. The runtime library then executes the interpreted code or loads and executes the load module. The product itself does not use databases.

It interacts with the z/OS and z/VM operating systems, which manage data storage through datasets and other storage mechanisms. The product does not have specific network port requirements. It operates within the z/OS and z/VM environments, which handle network communication based on system configurations.

Security is managed by the underlying z/OS and z/VM systems, which support RBAC and ACLs. Audit and logging are provided by the z/OS and z/VM systems. The product integrates with existing security infrastructure through the z/OS and z/VM security features.
