41. Vladimir Zabrodsky: An Introduction To The Rexx Programming Language I will concentrate only on features of the Rexx language which are not included, in whole, in the others programming languages. http://dhost.info/zabrodskyvlada/introrexx.html

AN INTRODUCTION TO THE REXX PROGRAMMING LANGUAGUE Rexx is used as a command language for operating, dialog, database management, network systems, as a scripting language for automating and integrating applications in these systems and as a macro language for arbitrary application programs. In this article I would like to show that Rexx is an interesting high-level programming language, too. This is an original introduction. I will concentrate only on features of the language Rexx which are not included, in whole, in the others programming languages. Instead the chapter "Types, Constants and Variables" Declarations or types are missing in Rexx programs because: All data are in the form of strings of characters. The meaning of a constant depends entirely on its usage. Operations are applicable on the basis of instantaneous values. A variable is a symbol that represents a value. Variables are considered to be varying-length character strings allowed to hold any binary value of any length between zero and an implementation maximum (the length of the evaluated result of an expression is limited by the available storage). Variables are automatically initialized at their first use. A variable which has not been assigned a value is not initialized. It will contain the default value of the symbol, which is the symbol's own name in uppercase letters. If the characters in a string form is a valid number, optionally with leading or trailing blanks, that string may participate in arithmetic operations. Numbers may be specified in exponential notation if desired.

Rexx Resources Class Notes REXX Study Program Our group has initiated a program to learn or improve our knowledge of the REXX programming language. The course of study will involve lectures on a topic at our monthly meetings, assignment of a set of problems on that topic, and then self-study in between meetings. Lesson notes and the problem sets will be posted on this page, so that members who cannot attend a meeting or OS/2 users from other parts of the world can participate. A message board has been set up for interaction between meetings so that peer-to-peer help will be available. This effort is collaborative and evolving, and it depends on the participation and suggestions of everyone who is interested. Lesson plans are being developed by member Barry Mann who is generously donating his time to this effort.

Some programming services are routines that let you interface with REXX and the language processor. In addition to the TSO/E REXX programming services that are described in this chapter, TSO/E also provides various routines that let you customize REXX processing. These are described beginning in TSO/E REXX customizing services . TSO/E also provides replaceable routines that handle system services. The routines are described in Replaceable routines and exits . Whenever you invoke a TSO/E REXX routine, there are general conventions relating to registers that are passed on the call, parameter lists, and return codes the routines return. General considerations for calling TSO/E REXX routines highlights several major considerations about calling REXX routines. The REXX programming services TSO/E provides are summarized below and are described in detail in the individual topics in this chapter.

47. Programming In REXX We think this is the best available indepth, platform-independent exposition of the REXX programming language. Unlike reference manuals that define REXX (and Mike Cowlishaw's http://www.quercus-sys.com/rexxbook.htm

Programming in REXX Here's a flattering, third-party review of the book from the online EDM/2 magazine. We think this is the best available in-depth, platform-independent exposition of the REXX programming language. Unlike reference manuals that define REXX (and Mike Cowlishaw's The REXX Language is very good in this regard), Programming in REXX has extensive explanation and motivation of the features of the language. The book covers all language details with concise examples and practical guidelines on how to write efficient, robust programs with any implementation of REXX. For example, there is a whole chapter that demystifies the many advanced capabilities of the PARSE instruction. Another chapter fully explains the REXX I/O model and supporting built-in functions. Other chapters go into character string handling, exception handling, and the INTERPRET instruction. Programming in REXX compares and contrasts REXX with other languages. It goes on to explore the most important REXX language idioms, instructions, and features; methods for facilitating program portability; tactics for debugging programs; and scores of other timesaving programming tips. The book also points out current weaknesses of the language, and how to work around them. The author is the developer of Personal REXX, which was the first commercial implementation of REXX outside of IBM.
