This document is an online version of the NetRexx language definition from Part 3 of The NetRexx Language. Please see that book for background information about the language, collected syntax diagrams, etc. A supplement to this document describes enhancements since 1.00.

This detailed description assumes that you have used the language or have read an overview of the language; if you have not, a good place to begin is the NetRexx Quick Start.

In this definition, the language is described first in terms of the characters from which it is composed and its low-level syntax, and then progressively through more complex constructions. Finally, special sections describe the semantics of the more complicated areas.
