IBM MAINFRAME: How to Run Rexx Macro?
Writing World-Wide Web CGI Scripts in REXX presented at the Spring 1996 SHARE Technical Conference, March 7, 1996, Anaheim California. The NetRexx Language Page provides information on an experimental project by Mike Cowlishaw (the autor of REXX) to create a Rexx front end to Java.
This web page attempts to fill a void for people wanting to create Rexx execs that will execute on any platform or Rexx implementation. It is geared toward the intermediate-advanced Rexx programmer and assumes some knowledge of the language. As you are probably aware, you can write general purpose Rexx execs which will execute anywhere with little or no changes.
Rexx (Restructured Extended Executor) is an interpreted programming language developed at IBM by Mike Cowlishaw. It is a structured, high-level programming language designed for ease of learning and reading. Proprietary and open source Rexx interpreters exist for a wide range of computing platforms; compilers exist for IBM mainframe computers. Rexx is used as a scripting and macro language.
REXX is similar to the C language in that it has a small number of instructions, but a large number of functions (and users can write their own functions). A description of the most important instructions are described on the following pages.
Summary: Learn how to write macros for PPWizard and use them to implement nifty and time-saving widgets for your web pages. Widgets and Macros. Catch-Up: If the instructions in this column make no sense to you then perhaps you need to freshen up on PPWizard and Rexx. Catch-up by reading these columns first: Dynamic Web Sites: Part I, Part II, Part III, Part IV.
VBA Substring Macro Example: Below I have created a macro that illustrates all the substring techniques available in VBA programming. This is a simple and self-explanatory macro, in this I have simply divided a text string with the 4 methods that I have described above. Below is the code that I have used for this macro.
A regular expression “engine” is a piece of software that can process regular expressions, trying to match the pattern to the given string. Usually, the engine is part of a larger application and you do not access the engine directly. Rather, the application will invoke it for you when needed, making sure the right regular expression is.
