About This Book

This programming guide explains how to use the \crexx{} Release 1 beta 1 toolchain in practice.

It focuses on the tools and workflows around Level B source:

• compiling .rexx with rxc
• assembling .rxas with rxas
• running .rxbin with the VM executables
• linking modules with rxlink
• packaging native executables with crexx -native and rxcpack
• using standard libraries, plugins, compiler exits, and integration APIs

The language itself is defined in the \crexx{} Language Reference. The lower level bytecode, assembly, and runtime model are described in the \crexx{} VM Specification.

Audience

This guide is for developers who want to build and run \crexx{} programs, integrate \crexx{} into tools, or understand how the command-line pieces fit together. Plugin and compiler-exit authors should read this guide together with the VM specification and the relevant public headers.
