1. Advanced REXX Programming Paper on advanced rexx programming. techniques for sharing data among a group ofrelated REXX programs; using OS/2 semaphores for coordinating access to data; http://www.quercus-sys.com/advrexx.htm

Paper on advanced REXX programming In May, 1994 Quercus Systems' Personal REXX developer Charles Daney wrote a paper on advanced REXX programming for presentation at the 1st Annual OS/2 World Conference in 1994, sponsored by Miller-Freeman. The paper was reprinted in the proceedings of the conference. Since the paper may be of interest to a much wider audience than those who attended the conference and received the proceedings, we are making it available here for download. The paper deals primarily with two topics. The first is how to structure data internally in a REXX program using various techniques for handling REXX compound variables, with special emphasis on using native REXX facilities for handling database-like applications without the use of an external database manager. Some of the subtopics covered include: how REXX allows structuring of data general explanation of REXX compound variables a detailed case study of managing a book database in REXX Quercus Systems' REXXLIB functions that facilitate working with compound variables The second main topic is how to structure REXX programs themselves into multiple files in order to realize the advantages of modularity. This includes the use of interprocess communication techniques for coordination among a group of REXX programs running as separate processes under OS/2.

Home Page About OS/2 Past Meetings Software We Use ... New Software 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. Your first step is to review the background information in the Outline of the REXX Group below. Then look at the lessons and problem sets below and begin working on the problems.

REXX Tips and Techniques Personal REXX has been on the market since 1985 - over 10 years. In that time, we have handled thousands of calls on our support lines, and read tens of thousands of messages about REXX in various online discussion groups, such as CompuServe and Usenet. Questions usually fall into one or two of a few categories, such as Implementation bugs Unexpected behavior of the REXX language Requests for instructions on how to perform some task using REXX Discussions of coding style Performance tuning Debugging techniques Requests for sources of more information about REXX Except for implementation bugs (which in Personal REXX we try to fix as soon as possible), the other sorts of questions appear over and over again. So, in the interest of saving everyone some time, we've tried to gather together some answers to the questions that arise most frequently. These are the topics that are currently addressed: Common REXX Pitfalls How-to Questions and Answers for REXX in OS/2 More will be added as time goes on.

Home My account Select a country All Software Products ... Operating Systems document.write(this.brandimage) PC DOS 2000’s REXX Programming Language PC DOS 2000 comes with the REstructured eXtended eXecutor language (REXX), a programming language that is easy to use for most users - especially users who are not programmers - yet flexible enough for computer professionals. REXX has been part of IBM's System/370 Virtual Machine/System Product (VM/SP) since 1983. Because of its ease of use and adaptability, REXX has since been included in VM, MVS, OS/400, OS/2, and now PC DOS. Why Use REXX? Here are several reasons for using REXX: It's easy to use by everyone. It helps speed up your repetitive, everyday tasks. Your program can interact with the user of the program. REXX enables you to write short programs with a minimum of overhead. The programs you write are portable to other platforms that have REXX, thus reducing overall programming effort. REXX helps you develop prototype applications and products. Why is REXX Easy to Use? REXX is easy to learn and use because it consists of meaningful English words. Anyone who has a command of the English language also has a command of the REXX language. REXX uses common English words such as SAY, PULL, IF ... THEN ... ELSE, DO ... END, and EXIT.

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.

This is nowhere near being complete. It just gets you going. For the complete story, contact me about courses in REXX. It’s just a taste of REXX. Start using it. Enjoy it. REXX is an interpreted language found in several environments, such as: Mainframe Midrange Other It is a high level procedural language. It is on the same level as procedural languages such as COBOL, FORTRAN, PLI and C. It is a complete programming language and includes facilities for reading and writing files, although it is limited to the simplest file structure: ordinary sequential files. Its strength lies in its ability to do string manipulation, the simplicity of its logic structures and in the presence of many built-in functions that take the place of complex instructions.
