The REXX Language on TSO

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/E, 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/E built-in functions, and the more important built-in REXX functions. You will find URLs in the book linking to a set of practice problems on a public webpage, as well as additional information on setting up your TSO/E session to execute REXX programs. This book was written and published in 2012 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.
