  REXX - Wikipedia, the free encyclopedia
REXX was designed and first implemented as an ‘own-time’ project between 20 March 1979 and mid-1982 by Mike Cowlishaw of IBM, originally as a scripting programming language to replace the languages EXEC and EXEC 2.
As such, REXX is considered a precursor to Tcl and Python.
Variables in REXX are typeless, and initially are evaluated as their names, in upper case.

 Rexx information for new users   (Site not responding. Last check: 2007-11-06)
Although Rexx has the capability to issue commands to its host environment and to call programs and functions written in other languages, Rexx is also designed to be independent of its supporting system software when such commands are kept to a minimum.
Rexx treats any instruction that it doesn't immediately recognise as an expression which it evaluates and passes to the host environment as a command.
Rexx can be used as an "application glue" language, in a manner similar to that in which shell scripts are often used.

 Rexx Language   (Site not responding. Last check: 2007-11-06)
REXX is a programming language designed by Michael Cowlishaw of IBM UK Laboratories.
In his own words: "REXX is a procedural language that allows programs and algorithms to be written in a clear and structured way." REXX doesn't look that different from any other procedural language.
What makes REXX different from most other languages is that it is also designed to be used as a macro language by arbitrary application programs.

 Six Rules of Thumb for Rexx
That is, REXX concatenates the two strings to form a *single* string which it then passes to SAY.
But in REXX, the way you call a subroutine (which is REXX's term for a procedure) is *completely* different from the way you call a function.
The REXX function "words" returns the number of blank-delimited words in a string, and "word(str, j)" returns the j-th such word in str.

 uni-REXX Product Description
Rexx is often embedded into other vendor- and user-written applications to provide macro programming and other customization capabilities.
The API's allow you to embed Rexx as a scripting language in applications written in C (or any compiled language that supports C data structures and calling sequences).
You may also extend the Rexx language by adding your own functions written in Rexx or C. uni-REXX includes a large sample library of general and UNIX-specific applications, illustrations of using the APIs to embed uni-REXX as a scripting language in compiled language applications, and an example of using uni-REXX for a client-server application.

 Rexx/Trans - Rexx Interpreter Translation Library   (Site not responding. Last check: 2007-11-06)
For those of you who have developed or are developing Rexx external function packages or applications that use Rexx, you only need to build your code against one Rexx API library and distribute one set of executables per platform.
When you link your Rexx application against an import library (or shared library) supplied with the Rexx interpreter, details about the Rexx API calls are embedded in your application or external function package.
On the first call to a Rexx API function, Rexx/Trans determines which Rexx interpreter to use (more on this later), and loads all entry points for the Rexx API functions into memory from the appropriate dynamic or shared library.

The downside of Rexx has always been its execution speed, its nearly always translated rather than compiled (but its no slower than Java).
Further problems emerge because it has numerous different implementations each using proprietary commands to overcome perceived limitations, especially in the file I/O and interface handling areas, this is mainly because it runs on so many different hardware platforms.
In this section I have tried to distil some basic Rexx information and list (as far as possible) the standard Rexx command set and as many special proprietary commands as I have come across.
