(IBM mainframe operating system environments). \u003cp\u003e\u003c\/p\u003eThe 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. \u003cp\u003e\u003c\/p\u003e\u003cbr\u003eThis book was written and published by the author of \"REXX in the TSO Environment.\" \u003cp\u003e\u003c\/p\u003eThe 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. \u003cp\u003e\u003c\/p\u003eREXX 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. \u003cp\u003e\u003c\/p\u003eREXX 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. \u003cp\u003e\u003c\/p\u003eREXX is generally not used for high-volume business applications because of its performance limitations with respect to compiled or assembled languages. \u003cp\u003e\u003c\/p\u003eREXX 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. \u003cp\u003e\u003c\/p\u003eThere is a chapter containing examples of REXX programs, macros, and user-written functions. Explanations of the code are shown on the facing page.","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Paperback","offer_id":45497545130135,"sku":"9781479104772","price":1952.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781479104772.webp?v=1767448230","url":"https:\/\/atlanticbooks.com\/products\/the-rexx-language-on-tso-9781479104772","provider":"Atlantic Books","version":"1.0","type":"link"}
