OS/390 TSO/E REXX Programming
This course discusses the background, structure, distinguishing characteristics, and major uses of the REXX language. It presents REXX strengths, features, versions, platforms and applications. It examines the structural units of REXX, from individual characters to complete programs, and discusses REXX program execution in different environments. Learn the basic components of the REXX language and its character groups. Become familiar with SAA and ANSI standards, and platforms that REXX supports. The course covers the assignment of variables and their use in REXX arithmetic and logical expressions. Learn about the operators accepted by REXX and about the priorities REXX uses in evaluating arithmetic and logical expressions.
TSO/E REXX Programming training covers such topics as:
EXEC Procedures
Debugging an EXEC Procedure
Advanced Techniques
REXX Built-in Functions
REXX in Various Environments
This course is designed application programmers, system programmers and system
administrators involved in the development of TSO/E applications

Description
This course discusses the background, structure, distinguishing characteristics,
and major uses of the REXX language. A survey of the range of REXX strengths,
features, versions, platforms and applications are presented. It also examines
the structural units of REXX, beginning with individual characters and progressing
to complete programs, with a discussion of REXX program execution in different
environments. The history of the REXX language, its nature and structure are
explored in this course. Starting at the basic component of the REXX language,
its character groups, students will examine the features of these individual
characters and the rules for combining them. Students will be able to define
SAA and ANSI standards, as well as identify platforms that REXX supports. The
assignment of variables and their use in REXX arithmetic and logical expressions
are also discussed. The significance of variables, and the REXX procedures
for assigning, modifying, undefining, and dis playing variables are covered.
The various arithmetic, logical, comparison, and concatenation operators accepted
by REXX, as well as the priorities REXX uses in evaluating arithmetic and logical
expressions are examined. Several REXX language built in functions used for
string and numeric formatting are introduced. This course is written to OS/390
2.x.
Audience
This course is designed application programmers, system programmers and system
administrators involved in the development of TSO/E applications.
