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.
