Down To Earth REXX is a fitting title for the book, in that it uses a wide array of practical, real-world programming examples in teaching REXX to all levels of programmers, from introductory concepts regarding REXX syntax, File Processing and Functions to more advanced RexxUtil Functions for MS DOS under Windows and OS/2 Workplace Shell and EPM Programming techniques.
Among some of the text-based programs presented in the book that I found useful as Windows-based MS DOS environment applications are an Interactive REXX Interpreter, a Calendar Month Display program, a File Deletion with Verification utility, a Binary File Hex Display utility, a Filespec Directory Search utility and a Multiple File Text String Search utility.
There are topics which cover ANSI.SYS programming for text-based color display programming, conversion of .BAT files into REXX programs, Compound variables for use in array processing, algorithms such as Zeller's Congruence (useful in date field processing) and the use of recursion for sorting, and .INI file processing techniques.
For the majority of the program examples (primarily Text Console-based) presented in the first 17 Chapters, the programs can be easily modified to run on different platforms (in my case I used IBM Object REXX for MS-DOS under Windows95 and Red Hat Linux 6.1 running a Gnome workstation terminal).Read more ›
All in all, this is a good book, and a useful addition to your library if you want to use REXX at home or at work.
Buy this book, but--unless you have access to OS/2--make sure you have one or two others first.
