REXX is a high-level programming language, developed in the 1970s. It was designed to be easy to learn and use, and to be suitable for both interactive use and writing programs to be run by other programs.
REXX is an interpreted language, which means that a program written in REXX can be run without being compiled first. This makes REXX programs portable, as they can be run on any system that has a REXX interpreter.
REXX has a number of features that make it particularly suited to text processing and system administration tasks. It has strong string handling capabilities, and its syntax is designed to be easy to read and understand.
REXX is also a very powerful programming language, with a rich set of built-in functions and operators. It can be used to write programs of any size, from simple scripts to complex applications.
Despite its many advantages, REXX is not widely used, due in part to the fact that it is not standardised. There are a number of different dialects of REXX, which are not compatible with each other. This can make it difficult to write portable programs that can be run on different systems.
Despite its drawbacks, REXX is a powerful and easy-to-use programming language that is well suited to a wide range of tasks. It is a good choice for anyone looking for an alternative to the more mainstream languages such as C and Java.
