22. Vladimir Zabrodsky: An Introduction To The Rexx Programming Language I will concentrate only on features of the Rexx language which are not included,in whole, in the others programming languages. http://www.geocities.com/SiliconValley/Garage/3323/introrexx.html

AN INTRODUCTION TO THE REXX PROGRAMMING LANGUAGUE Rexx is used as a command language for operating, dialog, database management, network systems, as a scripting language for automating and integrating applications in these systems and as a macro language for arbitrary application programs. In this article I would like to show that Rexx is an interesting high-level programming language, too. This is an original introduction. I will concentrate only on features of the language Rexx which are not included, in whole, in the others programming languages. Instead the chapter "Types, Constants and Variables" Declarations or types are missing in Rexx programs because: All data are in the form of strings of characters. The meaning of a constant depends entirely on its usage. Operations are applicable on the basis of instantaneous values. A variable is a symbol that represents a value. Variables are considered to be varying-length character strings allowed to hold any binary value of any length between zero and an implementation maximum (the length of the evaluated result of an expression is limited by the available storage). Variables are automatically initialized at their first use. A variable which has not been assigned a value is not initialized. It will contain the default value of the symbol, which is the symbol's own name in uppercase letters. If the characters in a string form is a valid number, optionally with leading or trailing blanks, that string may participate in arithmetic operations. Numbers may be specified in exponential notation if desired.

The American Programmer Home Programming Books for Computer Professionals Privacy ... Programming > The REXX Files The REXX Files The Truth about REXX is out there. And in here. REXX is a scripting language found in many platforms, including MVS, OS/390, Z/OS, CMS, VSE, CICS, OS/2, Windows, Unix, Linux, AS/400, and others. REXX is generally interpreted, which makes development easy, but gives a performance penalty. Compilers are available for REXX. REXX has all the facilities of a complete programming language. REXX is particularly good for processing data strings. REXX is not datatyped: all variables may contain any type of data. REXX data is either character (string) data or numeric. There is only one type of numeric data in REXX. Numeric data in REXX is processed internally in floating decimal format, so conversion does not take place. There is information here about REXX books and programming. The REXX Language on TSO REXX Reference Book The REXX Language on TSO By Gabriel F.

uni-REXX Product Description Home Products Downloads Support ... Company uni-REXX Product Links New Release FAQ Documentation Product Support uni-REXX is a UNIX implementation of IBM's System Control Language, Rexx. It originated in the MVS/TSO and VM/CMS operating systems, where it is used for macro programming, personal productivity programming, and general applications development. It is also used as a macro and programming language within many other applications, including the ISPF editor and Dialog Management Services, and VM/CMS's System Product Editor, XEDIT. Rexx is often embedded into other vendor- and user-written applications to provide macro programming and other customization capabilities. uni-REXX is an ANSI standard implementation of the Rexx language for UNIX systems. By using uni-REXX with UNIX, mainframe Information Services personnel who must now use and manage UNIX can avoid the huge learning curve associated with the UNIX shell languages (and their equally cryptic UNIX-derived alternatives such as PERL) becoming immediately productive in the new environment. Where Rexx has been used to implement business applications, or embedded into larger applications, uni-REXX is a critical component in porting those applications to UNIX. uni-REXX also provides system managers and personal productivity users a familiar capability in the new environment.
