Rexx Plug-in Functions The WarpDoctor Rexx Plug-in supplies a number of Rexx functions for communicating with the plug-in. Each of those functions are listed below. The behavior of the functions can be modified by the Rexx variable wdPlugin.errorSwitch If the variable is not present, or if it is set to (zero) then the functions return errors as part of the normal Rexx return value. When wdPlugin.errorSwitch = 1 any errors encountered by any functions will result in a Rexx syntax error. You can pick up this syntax error using the Rexx signal on syntax statement. Loads (registers) all the Rexx plug-in functions. This should be called at the top of the Rexx program, for programs that run in a separate session. It does not hurt for this function to also be called from programs that run as a macro of the plug-in. call RxFuncAdd 'wdPluginLoad', 'wdPlugin', 'wdPluginLoad' call wdPluginLoad Initializes the plug-in environment for the Rexx program, and creates the Rexx stem variables wdEmbed. and wdMainArgs.

The Codesmith's Library Written by Carsten Whimster The Codesmith's Library In The Codesmith's Library, I focus on development books and materials. I have written this column from the point of view of an intermediate PM C programmer and intermediate REXX programmer. Pick up whichever book strikes your fancy, and join the growing group of people following our PM programming columns. I have already reviewed a number of beginner's books, and will try to concentrate a bit more on intermediate techniques and special topics from now on. Please send me your comments and thoughts so that I can make this column what you want it to be. I read and respond to all mail. Programming In REXX is an introductory book from the J. Ranade Series of mini- and mainframe computer books. Of course, this particular book is not about minicomputers or mainframes, but rather about learning portable, standard REXX. Errata I have added a "Book Errors" page to the site, and put a link directly in the column of each issue, to let you see these errors and to let you judge for yourself how serious they are. If anyone has found any errors in this or any other books, please pass them on, and we can keep track of them here. A central site to check for errors would be very beneficial, I feel, so hopefully we can do this thing together. I have personally started a Web page called "The OS/2 API Project". It is accessible from my normal homepage listed on my author page. The purpose of this page is to promote The OS/2 API Project, and to give it a temporary home. Eventually I hope to have this page on the EDM/2 site, but until we get more space, it'll stay where it is. The OS/2 API Project is a documentation project which eventually aims at covering the whole available OS/2 API, from Dev functions to Wps functions, from messages to structures, and from define's to include's. Please access the site to find more information. Also look for the upcoming announcement in both EDM/2 and on various comp.os.os2.* newsgroups. So far, I have two other contributors, but with three people it will take a long time to come together, so we need all able- handed people to type up their favorite APIs for this project.

OS/2 Warp FAQ List (20 Feb 95) 0.9b (c) 1995 Peter Childs (5.11) REXX How do I use REXX? What does it do? REXX is built into every copy of OS/2 Warp (where it is also known as Procedures Language/2). It is a general purpose, interpreted programming language which was first released on IBM mainframes over a decade ago. REXX is extremely easy to learn and use. It is particularly strong at string manipulation, and it has features which are difficult to implement in compiled languages (like the ability to read its own source code or execute a string as a command). OS/2 Warp applications can use REXX as a common scripting language, which means that users need not learn separate macro or script languages for each application. For example, the OS/2 Warp versions of Lotus 1-2-3 and Borland ObjectVision will interface with REXX. OS/2 Warp's multimedia extensions (MMPM/2) contain a REXX interface, so REXX programs can play, record, and manipulate sound and video files. And REXX can be used to create complex batch files (with interactive prompting), since it is integrated so tightly into OS/2 Warp's command processor. Moreover, a trio of REXX visual builders (programming tools which help create even complex REXX applications quickly and easily using simple, drag and drop manipulation of on screen objects), HockWare's VisPro/REXX, Watcom's VX REXX, and Gpf REXX, are now available. For more information on OS/2 Warp's REXX interpreter, see the REXX Information online documentation located in the Information folder.

EXTERNAL DATA QUEUE Please, give us tools that encourage us to write better programs, by enhancing our pleasure when we do so. D ONALD E. K NUTH in CACM No. 12 1974, p. 672 I introduce to you in detail external data queue (I don't suppose your knowledge about this feature of the Rexx language) - as a device for interprogram communication, as an input or output device, as useful data structure: stack or queue or deque (double-ended queue) ... The external data queue is an AS/400 object that consists of a series of entries similar to database records. When a job is started (in interactive mode after login - SIGN ON ), the queueing services are immediately made available to the job. These services remain available until the job ends (in interactive mode by the SIGNOFF command). Similarly, entries placed on the queue will remain on the queue and be available until explicitly removed or until the job is ended. After starting a job, any program that is part of the job can continue to use any of the queuing services until the job ends. Thus, one program can place an entry on the queue and end. Another following program can then receive what was placed in the queue at a later time. This can serve as a device for inter-program communication. A helpful analogy is to think of the external data queue of a hose of a vacuum cleaner (see on the next picture); you can placed ping-pong balls as entries at the front of the hose or at the end of the hose; but you can retrieved a ball only from the front of the hose

Introduction to REXX REXX is a high level programming language designed to perform in two important roles as an agent for computer users and system administrators: As an integrator of system commands and other programs into composites intended to handle specific higher level functions As an embeded macro language for customization or augmentation of system commands such as the system editor REXX provides a clean, consistent syntax which many end-users have found easy to use as they strive to adapt computers to their needs. At the same time, computing professionals have found the language sufficient to accomplish complex tasks with a programmer productivity many times that of traditional macro and scripting languages. REXX has been available for nearly a decade from IBM and other vendors for operating systems ranging from PCDOS, OS/2, and the Amiga on the desk top thru UNIX(tm) to IBM mainframe VM and MVS systems in the glass house . It biggest defect has probably been its ease of application to production problems where a traditional compiled high-level might have been more appropriate. The purpose of these pages is to introduce S/REXX Benaroya 's implementation of REXX for UNIX environments with an overview of those features which differentiate S/REXX from other implementations.

SPSS SAS Rexx Programs ... Perl Programs SPSS SPSS stores dates internally as the number of seconds since midnight, October 14, 1582, which was the first day of the Gregorian Calendar. The built-in variable $time contains the current date and time in that format, as an integer quantity. (Actually, all quantities in SPSS are stored as 64-bit floating point numbers. This allows for 56 bits of precision, which avoids the 2037 problem that Unix has with its 32-bit integer.) SPSS has several date and time format codes that will print these huge numbers as human-readable dates and times, such as DATE11 which is the British-English literary style, but it does not have one for ISO format. You can construct a string variable containing the date in ISO format with the following SPSS language commands:
