Summary: good book, lousy deal
Review: I enjoyed the book. It is very well written as a reference for the language. And it is interesting to read the motivation behind different features. I first used Rexx about 18 years ago, and I still think it's an excellent scripting language. I use the Korn shell every day, but I find it much easier to write scripts in Rexx. However, I don't think this is a good deal. [The cost] is WAY too much to spend for a xeroxed paperback copy. [Also,] it's NOT in a textbook binding...

Summary: no laurels to rest on
Review: I first used REXX back in 1982 when it was called REX. In those days, since it provided a decently structured interface to a very clumsy executive (VM/SP with CMS), we all marveled at the language. Today, it is clumsy at best. The author's claims that the language is "designed for people, not machines" make it sound as if he has achieved some magical apotheosis. He has not. As reasonably structured "glue" for an archaic operating system environment, REXX makes a stab at being an equal of the Korn shell but misses the mark. I wouldn't go any farther than that in trumpeting its power, flexibility, or elegance.

Summary: The perfect book for a REXX beginner.
Review: I used this book as my bible for the first 3-4 months I worked in REXX. It contains all of the introductory lessons and information you need to get some REXX under your belt. Perfect for a first-time REXX programmer.

Summary: Concise Book Written By The Creator Of Rexx
Review: This is a great reference book for the rexx programming language.However based on the current price I'm glad I was able to find my old copy from back in the 90's which has the original cover. An interersting aspect of this book is the history of how the rexx language was created. It was originally distributed internally within IBM and many changes were made based on feedback from the original users. This is a good example of how someone managed a tremendous amount of information. The reference documentation was written before the language was actually implemented. The author felt that writing the reference documentation after the language was implemented would result in inaccurate documentation because the writer would know the implementation too well to write an objective description. He says the following about the thousands of e-mails he received from the original users: "All of this mail was reviewed some time after the initial correspondence in an effort to perceive trends and generalities that might not have been apparent on a day-to-day basis." I guess this is similar to how things evolve in the unix world.
Something gets introduced on some newsgroup and then it evolves. Anyway the end result is a relatively easy-to-understand programming language which fills a certain type of niche functionality very well. Rexx is sort of like a scripting or command language but it has many of the same features as a full blown programming language plus some of its own unique features. It's definitely a better alternative than batch files for working with files and issuing commands to the operating system.
