Rexx
Programmer′s Reference
Whether you′re new to Rexx or are an experienced Rexx programmer, this comprehensive reference offers you what you need to know in order to work with this easy yet powerful scripting language on any level. After a quick overview of the basics of Rexx, you′ll move on to more advanced scripting topics such as portable code and optimal coding style.
Later chapters cover the most common Rexx interfaces and tools and introduce and demonstrate how to use Rexx with operating systems, SQL databases, Web servers, and XML. You′ll also learn about the many free Rexx interpreters and the unique advantages of each. By the end of the book, you′ll have learned special techniques that you can use to make the most of the power and flexibility of Rexx.
What you will learn from this bookThe entire Rexx language, from an introductory tutorial to advanced featuresHow to script with Windows®, Linux®, Unix®, and mainframesHow to interface Rexx to databases, Web servers, GUIs, XML, and other toolsObject–oriented programming with the object–oriented Rexx interpretersHow to script in the Java environment with NetRexxHow to script handhelds running Windows CE, Palm OS®, or Symbian/EPOC
Who this book is for
This book is for programmers on any platform who are either looking to learn Rexx or already use it and want to expand their knowledge of Rexx. A basic knowledge of programming is assumed.
"This timely book is an excellent introduction to Rexx and all its implementations. It truly deserves space on any Rexx programmer′s bookshelf."
