This Webinars is an overview of the 3 day WA1933 Using REXX under TSO/ISPF course. We show and explain several REXX language features. REXX is a powerful multi-purpose and user-friendly programming tool used to exploit many IBM and third-party operational products. It is the tool of choice in most (if not all) of today’s larger data centres for those who need to implement new operational procedures both quickly and effectively. This three-day course is designed for TSO/ISPF users who wish to learn how to create and use programs in the REXX language. The course is taught combining classroom tuition with many practical exercises and problem scenarios, thus ensuring a full understanding. Prerequisites – An understanding of programming at a conceptual level and a good knowledge of TSO and its commands. A superficial knowledge of ISPF/PDF is insufficient for those who wish to gain full value from this course. Audience – Systems programmers, operations analysts, senior operators, operations support staff and application programmers who will be writing and/or maintaining TSO REXX programs.
