This book will teach you how to write programs in the REXX language on IBM mainframe computers. It is useful for technical, applications, and maintenance programmers working on new or legacy code written in the REXX language. It describes the REXX programming language for TSO, MVS, OS/390 and z/OS. (IBM mainframe operating system environments). The book quickly gets you writing programs in REXX. It covers all REXX language elements, all TSO built-in functions, and the more important built-in REXX functions. This book was written and published by the author of "REXX in the TSO Environment." The REXX Language on TSO improves on "REXX in the TSO Environment" in every way: it clarifies important points; it is better organized, and gives better examples. REXX is a high-level scripting language created in the 1980's by IBM for the IBM mainframe operating systems CMS and MVS. It quickly gained popularity and expanded into other environments such as Netview, CICS, AIX, QMF, VSE. REXX is often used for prototyping applications, front-ending operating system commands and TSO/ISPF panel applications. Its flexibility and clear straightforward syntax make it a welcome replacement for IBM utility programs. REXX is generally not used for high-volume business applications because of its performance limitations with respect to compiled or assembled languages. REXX is able to read and write sequential files and/or PDS members. It contains all programming language features, including the ability to do calculations with decimal numbers to any precision. It is especially useful in manipulating character strings in free-column format. There is a chapter containing examples of REXX programs, macros, and user-written functions. Explanations of the code are shown on the facing page.

It's for people who know some French, and want to know and use more popular expressions, just like the French. Here are some of the 157 French expressions contained in this book: l'arrache, la bonne franquette, la fortune du pot, plat cul, tout bout de champ, Accro, Accroc, Accrochage, Attacher lundi avec mardi, Au compte-gouttes, a m' tonnerait, a ne s'invente pas, Canicule, coper d'une amende, En catimini, tre de m che, Laissez-moi faire appel vos lumi res, Faire des pompes, Faire la poule mouill e, Garde altern e, Inconditionnels, Incontournable, Informatique en nuage, Je constate, seulement, Je l'ai oubli chez ma tante, Je m'en doutais, Je mets mon grain de sel, La ceinture de V nus, La coqueluche du moment, Laissons le pass tre le pass , L' ne de Buridan, Le cul dans le beurre, Le pactole, Migraine du froid, Miroir aux alouettes, Niche fiscale, Paradis fiscal, Passer comme une lettre la poste, Passer en coup de vent, P pin d'ordinateur, Perdre la boule, Picoler en douce, Pierre Paul et Jacques, Rond comme une queue de pelle, Ratissage minutieux, Rentrer bredouille, Rester casanier, Retourner dans leurs tombes, Se b coter, Se cr per le chignon, Se faire du mouron, Se faire sonner les cloches, Se retourner dans leurs tombes, Sortir de ses gonds, Tape-cul, Tourner du chapeau, Tuer le ver, Avoir une case en moins, Vivre aux crochets de quelqu'un, Vol l'arrach , l'arrach . Some of the expressions are pure slang, others are sayings or proverbs, but all are popular French expressions that French people use all the time. Read the book, and start using them when you speak French.

The REXX programming language includes built-in functions that simplify programming. REXX Functions let you manipulate data strings or do mathematics simply with a minimum of programming effort.This book explains 78 REXX functions that you can use in your REXX programs. This book is about z/OS TSO REXX functions. A function is a built-in feature of the REXX language. Functions are always available to you when you are writing your program. They provide an easy way to manipulate data strings or to perform arithmetic on numbers. Using functions simplifies programming and provides reliability, because the functions were created and tested by the software manufacturer (IBM.) The Index is not like most indexes that list only language features alphabetically. They are no help if you don't know the name of the language feature. This index shows the common English language name for a feature, for example, "Convert decimal number" points you to the REXX equivalent D2C. You don't have to know that D2C means "Convert decimal number to character" in order to use the index. The examples are simple and clear and will show you the different ways to invoke, or use REXX functions in a REXX program. To aid you in finding the function that you need, one chapter is devoted to listing the functions, classified by what they do. Each of the built-in functions is shown in detail with examples of use. The functions are shown alphabetically.As a bonus, I've included several supplementary chapters to make life easier for the REXX programmer: 1. How to write REXX macros.2. Compatibility Issues across platforms.3. Precedence of Operators. What REXX processes first, in complex expressions?4. How to execute TSO Commands, in Native Mode (Ready Mode) TSO, in ISPF Option 6, on the command line on ISPF panels, and in batch.5. How to specify Dataset names in TSO commands, in REXX, and CLISTs. An explanation of TSO naming conventions.6. The TSO commands that you are likely to use in your REXX programs, arranged by their function, with clear and simple examples.
This book is for the programmer who needs to convert a program written in TSO-CLIST to TSO-REXX in the z/OS TSO/ISPF environment. You need some familiarity with both languages in order to do a conversion.This book will show the correspondences, or lack of them, between CLIST language features and REXX language features. CLIST language features are shown on the left-hand page, with the corresponding REXX language feature on the facing, right-hand page.TSO-CLIST dates back to the beginning of TSO in 1971. It truly is a legacy language. IBM continues to support it because so many of its customers have active, functioning CLIST programs in use.CLIST language is found only in one environment, the z/OS TSO/ISPF environment. Experience programming with CLIST is not readily transferable to any other environment. The REXX language is found mostly in the z/OS TSO/ISPF environment, and in QMF, CICS, DOS/VSE, and Netview. Knowing REXX makes you more valuable to your employer.The number of programmers who can understand CLIST language is diminishing. It is a good business decision to convert CLIST programs, where possible, to REXX programs.I'm sure most programmers will remember the nightmare of having to fix a program that is so old that no one left alive knows what the program is expected to do.
