http://en.wikipedia.org/wiki/Rexx Rexx (Restructured Extended Executor) is an interpreted programming language dev eloped at IBM by Mike Cowlishaw. It is a structured, high-level programming lang uage 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.[2] Rexx is widely used as a scripting and macro language, and is often used for pro cessing data and text and generating reports; these similarities with Perl mean that Rexx works well in Common Gateway Interface (CGI) programming and it is ind eed used for this purpose. Rexx is the primary scripting language in some operat ing systems, e.g. OS/2, MVS, VM, AmigaOS, and is also used as an internal macro language in some other software, such as KEDIT, THE and the ZOC terminal emulato r. Additionally, the Rexx language can be used for scripting and macros in any p rogram that uses Windows Scripting Host ActiveX scripting engines languages (e.g . VBScript and JScript) if one of the Rexx engines is installed. Rexx is supplied with VM/SP on up, TSO/E Version 2 on up, OS/2 (1.3 on up), Amig aOS Version 2 on up, PC DOS (7.0 or 2000), and Windows NT 4.0 (Resource Kit: Reg ina). REXX scripts for OS/2 share the filename extension .cmd with other scripti ng languages, and the first line of the script specifies the interpreter to be u sed. A Rexx script or command is sometimes referred to as an EXEC in a nod to Rexx's role as a replacement for the older EXEC command language on CP/CMS and VM/370 a nd . Rexx is the primary scripting language in some operating systems, e.g. OS/2 , MVS, VM, AmigaOS, and is also used as an internal macro language in some other software, such as KEDIT, THE and the ZOC terminal emulator. Additionally, the R exx language can be used for scripting and macros in any program that uses Windo ws Scripting Host ActiveX scripting engines languages (e.g. VBScript and JScript ) if one of the Rexx engines is instals Scripting Host ActiveX scripting engines languages (e.g. VBScript and JScript) if one of the Rexx engines is installed.E XEC 2s Scripting Host ActiveX scripting engines languages (e.g. VBScript and JSc ript) if one of the Rexx engines is installed.EXEC 2led.EXEC 2 command language on VM/SP.ipting Host ActiveX scripting engines languages (e.g. VBScript and JScr ipt) if one of the Rexx engines is installed.
