Elements of ARexx - Chapter 3

This chapter introduces the rules and concepts that make up the ARexx programming language and explains how ARexx interprets the characters and words used in programs. The different elements that are explained include:

• Tokens - the smallest element of the ARexx language
• Clauses - the smallest executable unit, similar to a sentence
• Expressions - a group of evaluated tokens
• The Command Interface - the process by which ARexx programs communicate with ARexx-compatible applications

This chapter also includes a discussion of the ARexx execution environment. This is intended for more advanced Amiga users and includes technical details on interprocess communication.
