This book isn't only for novices. Tasks of all levels are included. From the Installation and Operations sections the reader will see the detailed steps for powering up and down, controlling the system console, and managing subsystems. There is an administration section that covers system values, printing, and PTF management. The system architecture section discusses libraries and library lists, files, and objects. Programming has its own section with chapters on DDS, CL, RPG, Java, and important IBM utilities. There is also a section on the Internet that covers the newer technologies. The fourth edition has had a complete update of all the chapters and adds a particularly rich set of new chapters as well. Topics like iSeries Navigator, WebSphere Application Server, SQL, Qshell, and performance are among the new chapters which will make this edition a good buy even for those who already own previous editions. The effective use of Control Language (CL) is a critical skill for anyone working with IBM's robust midrange eServer family (i5, iSeries, and AS/400). But why settle for just enough CL knowledge to get by? From the simplest task to the most complex process, CL is at the heart of your server. Become a CL guru and fully leverage the abilities of your system. All it takes is a little time, effort, and Complete CL, 4th Edition.

With this book, you will master CL and extend the capabilities of your i5/iSeries. Programmers, operators, security officers, system administrators, or any IT professional working with OS/400 and i5/OS will benefit greatly by reading this book.

Complete CL, The Definitive Control Language Programming Gui - 2000-07-06
Reviewer Rating:
Simple, yet very detailed, lots of code samples and some very useful utilities. As anything from Midrange Computing, slightly overpriced. Get your IT department to pay for it!

This book lives up to the quality we expect from Ted & Ernie - 2005-07-29
Reviewer Rating:
This book is an excellent book even for seasoned veterans on the iSeries. I found at many tips and examples that were very valuable. Ted Holt always manages to keep one step ahead of the game and provide insight into CL, RPG and iSeries in general.

I have been following Ted & Ernies technical articles for years and I would recommend this book to any of my colleagues.
It seems Ted always strives to give the iSeries community his best.

I was sad to hear that Ernie Malaga had passed away.

Thanks to Ted & Ernie...again

Excellent reference from trusted names - 2008-01-14

I feel as if I am one of the few S/36 programmers left. My company has upgraded to the I5, and I am still supporting S/36 code on it. This book is a terrific reference for integrating CL into existing legacy code and utilizing the extraordinary power of the new machines in old systems. The section on S/36, I believe, was written JUST FOR ME!!! I trusted the book when I bought it, because I have relied on Ted and Ernie throughout my midrange computer career, from S/3 model 10 through the latest "machine to surpass all machines". Thanks to Ted and Ernie!!!
