Previous topic Next topic Contents Index ... PDF REXX programming hints and tips z/OS V1R10.0 Communications Server IP Sockets Application Programming Interface Guide and Reference Capitalization Throughout the documentation, REXX socket API commands and constants are capitalized when they are used in descriptive text. For example, the LISTEN command places a socket descriptor in passive mode. Quotation marks Throughout the documentation, REXX socket API commands and constants are enclosed in quotation marks (") when they are used in code examples, for example, src = socket("ACCEPT",sockfd); Although the use of quotation marks is optional, consider using quotation marks to prevent programming errors. Using quotation marks forces the socket function to use string literals rather than REXX variables. When REXX encounters an uninitialized variable, it initializes that variable with the name of the variable. The command socket(ACCEPT, sockid is valid because the uninitialized variable ACCEPT is initialized to the character string ACCEPT. However, if the program initializes the ACCEPT variable with a value other than the character string ACCEPT, the socket function fails. Guideline: Unless otherwise indicated by a specific socket command, all socket commands and constant values must be passed as character strings.

Both proprietary and open source interpreters for REXX are available on a wide range of computing platforms, and compilers are available for IBM mainframes. Rexx is widely used as a glue language macro language, and is often used for processing data and text and generating reports; these similarities with Perl mean that Rexx works well in CGI programming and it is indeed used for this purpose. Rexx is also used as an internal macro language in some software including the ZOC terminal emulator. Additionally, the Rexx language can be used for scripting and macros in any programme which uses Windows Scripting Host ActiveX scripting engines languages (e.g. VBScript and JScript) if one of the Rexx engines (see below) are installed.

Current Beta: N/A Download Documentation Bug Report Home ... RxSock Rexx/Wrapper Overview Rexx/Wrapper is a tool that wraps Rexx source or tokenised code into an executable. The Rexx source code can be optionally compressed and encoded to ensure that the original Rexx code cannot be viewed (unless you have the original encryption key). To use Rexx/Wrapper you need two extra bits of software: A supported Rexx interpreter A supported C compiler See the Rexx/Wrapper documentation for further details. Support With Rexx/Wrapper on SourceForge, support resources for Rexx/Wrapper . such as mailing lists, discussion forums, bug reporting and feature requests are available. Rexx/Wrapper is freeware, distributed under the GNU General Public License Not a Compiler Rexx/Wrapper is not a compiler. It does not compile the Rexx code into native machine code; the Rexx code is still interpreted by a Rexx interpreter. Mark Hessling mark@rexx.org

Faster than wcount.rex chkcol.rex Checks tabular text files for consistent column boundaries. This is useful when imported tabular text files into Excel or Access. combsort.rex Performs a sort using the COMBSORT method. I first saw this in Byte magazine in Pascal. This is a relatively simple, relatively fast sort algorithm. combstem.rex Demonstrates how to use combsort.rex with the stem specified externally. csort2.rex For sorting one array, and rearranging another array based on the order of the first array.

19. TinyVM: NetRexx For Lego RCX How to run NetRexx programs in the Lego Mindstorms RCX. http://tinyvm.sourceforge.net/netrexx.html

TinyVM: NetRexx for Lego RCX This page describes how to run NetRexx programs in the Lego Mindstorms TM RCX, which is part of Lego's Robotics Invention System. This is achieved with the help of the TinyVM system. Requirements This has been tested on CygWin with JDK 1.2.2 and TinyVM 0.2.1. Other setups should also work. Same requirements as TinyVM. See User's Guide Setup Download TinyVM 0.2.1+ and install it as usual. Download NetRexx . You only need to unzip the file. You may want to create a compilation script, e.g. tvmnrxc , which may look like this: Example Follow these instructions to run a simple program that continuously displays the raw value of sensor 2. Download the firmware, if you haven't done so yet, with tvmfirmdl Copy the following NetRexx program into a file named sensors.nrx Set CLASSPATH to . (dot). Compile sensors.nrx with your NetRexx compilation script. Download program with tvmld sensors -d You can press Run as soon as the standing man figure appears. Limitations In addition to TinyVM's limitations, you won't be able to use all of the NetRexx constructs, e.g. the say command. In most cases, the linker will complain if you try to use these constructs.

20. Advanced REXX Programming Paper on advanced REXX programming. In May, 1994 Quercus Systems' Personal REXX developer Charles Daney wrote a paper on advanced REXX programming for presentation at the 1st http://www.quercus-sys.com/advrexx.htm

Paper on advanced REXX programming In May, 1994 Quercus Systems' Personal REXX developer Charles Daney wrote a paper on advanced REXX programming for presentation at the 1st Annual OS/2 World Conference in 1994, sponsored by Miller-Freeman. The paper was reprinted in the proceedings of the conference. Since the paper may be of interest to a much wider audience than those who attended the conference and received the proceedings, we are making it available here for download. The paper deals primarily with two topics. The first is how to structure data internally in a REXX program using various techniques for handling REXX compound variables, with special emphasis on using native REXX facilities for handling database-like applications without the use of an external database manager. Some of the subtopics covered include: how REXX allows structuring of data general explanation of REXX compound variables a detailed case study of managing a book database in REXX Quercus Systems' REXXLIB functions that facilitate working with compound variables The second main topic is how to structure REXX programs themselves into multiple files in order to realize the advantages of modularity. This includes the use of interprocess communication techniques for coordination among a group of REXX programs running as separate processes under OS/2.
