Getting Started in REXX


A REXX procedure is a program that consists of a series of tasks in one 
common processing file or batch file. 
Many languages can be used to write programs. BASIC, which is widely used 
in home computing, has very few rules, but it requires writing many lines 
of code for an intricate program.  Languages such as PL/1, COBOL, C, APL, 
and PASCAL have more rules, but allow you to write more functions in fewer 
lines. 
REXX combines the simplicity of a programming language such as BASIC with 
features that exist in more powerful languages such as writing fewer 
lines.  It is easier to learn, because it uses familiar words and 
concepts.  REXX allows you to do simple tasks, yet has the ability to 
handle complex tasks. 
To get started in REXX, you need: 
   o  A Personal Computer with OS/2 Version 2.0 (or a later version of 
      OS/2) installed.  REXX works only in OS/2 sessions. 
   o  Knowledge about using a text editor. 
 
 Many of us learn by looking at examples, so examples of REXX procedures 
 are provided in this presentation. First look at the procedure, then 
 study the explanation of the examples to see what the procedure contains. 
  If you like, try the procedure to see how it works.
