The REXX language is a versatile general-purpose programming language that can be used by new and experienced programmers. This part of the book is for programmers who want to learn the REXX language.

The REstructured eXtended eXecutor (REXX) language is a high-level procedures language that enables inexperienced users as well as experienced programmers to combine REXX instructions and host commands and services into programs called REXX execs.

Rexx (restructured extended executor) is a high-level programming language developed at IBM by Mike Cowlishaw. [6] [7] Both proprietary and open source Rexx interpreters exist for a wide range of computing platforms, and compilers exist for IBM mainframe computers. [8] Rexx is used for scripting, application macros and application development.

REXX (Restructured EXtended eXecutor) is a powerful interactive programming language that can execute system commands, such as TSO, ISPF etc. It allows you to: Request information from the terminal and Display output on terminal. Execute TSO commands under program control. Develop custom-made utilities. Read and write files.

Explain the Rexx Functions (User Defined & Build-in) and Subroutines (Internal & External). Explain Stacks and Queues. Handle TSO/E Commands and File Operations. Explain ISPF Tables and Panels. Rexx Tutorial - Rexx is a programming language that is extremely versatile.

2 天之前 · Welcome to the Rexx Language page at IBM Hursley. This page links to documents relating to the Rexx, Object Rexx, and NetRexx programming languages (so what's NetRexx?), gleaned from many sources.

REXX can perform file operations using TSO commands, Datasets can be created, allocated, read and written using REXX. ALLOC command is used to create / allocate datasets. EXECIO command is used to read and write datasets.

The REXX language is a versatile general-purpose programming language that can be used by new and experienced programmers. This part of the book is for programmers who want to learn the REXX language.

Restructured Extended Executor (REXX) is the i5/OS implementation of the Systems Application Architecture® Procedures Language. REXX is a programming language that is supported by an interpreter provided as part of the i5/OS licensed program. This guide provides a wide-range discussion of programming with REXX.

This course is designed to teach you the basic skills required to write programs using the REXX language in z/OS. The course covers the TSO extensions to REXX and interaction with other environments such as the MVS console, running REXX in batch jobs, and compiling REXX.
