The REXX language has an extensive library of functions known as built-in functions. There are two classes of built-in functions: those which are part of SAA (Systems Application Architecture); additio...doi:10.1007/978-1-4471-0755-2_10MSc (Hons) Anthony S. Rudd BSc...

For example, Rexx is free-format and case-insensitive. It has very little syntax and a tiny instruction set. Yet its large built-in function set makes it powerful. And external functions are accessed just like built-in functions. Rexx scripts easily leverage existing code, in the form of pr...
