Publisher's Synopsis
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 78 REXX functions that you can use in your REXX programs. This book is about z/OS TSO REXX functions.
As a bonus, I've included several supplementary chapters to make life easier for the REXX programmer: 1. How to write REXX macros.
2. Compatibility Issues across platforms.
3. Precedence of Operators. What REXX processes first, in complex expressions?
4. How to execute TSO Commands, in Native Mode (Ready Mode) TSO, in ISPF Option 6, on the command line on ISPF panels, and in batch.
5. How to specify Dataset names in TSO commands, in REXX, and CLISTs. An explanation of TSO naming conventions.
6. The TSO commands that you are likely to use in your REXX programs, arranged by their function, with clear and simple examples.
