The REXX programming language includes built-in functions that simplify programming. REXX Functions let you manipulate data strings or do mathematics simply with a minimum of programming effort. This book explains 72 REXX functions that you can use in your REXX programs. This book is about TSO REXX functions. The examples are simple and clear and will show you how to use REXX functions in your programs. A function is a built-in feature of the REXX language. Functions are always available to you when you are writing your program. They provide an easy way to manipulate data strings or to perform arithmetic on numbers. Using functions simplifies programming and provides reliability, because the functions were created and tested by the software manufacturer (IBM.) The Index is not like most indexes that list only language features alphabetically. They are no help if you don't know the name of the language feature. This index shows the common English language name for a feature, for example, "Convert decimal number" points you to the REXX equivalent D2C. You don't have to know that D2C means "Convert decimal number to character" in order to use the index. As a bonus, I've included chapters on writing REXX macros, the precedence of operators, and TSO line-mode, or "ready mode" commands.
