Writing to output dataset using REXX - REXX - Tek-Tips.
Save the REXX program and run it. Exercise 3 For this exercise create member EX3 in your REXX Library. Goal: The same as Exercise 2 but this time capture the output and display it inside a loop. Hint: Use OUTTRAP and a DO END loop. Save the REXX program and run it. Exercise 4 For this exercise create member EX4 in your REXX Library.
For example, suppose that you want to respond to a host message by issuing a display command, comparing the display output with the original message text, and then responding to the original message. Managing such a complicated response is beyond the scope of rules, but you can do it through a REXX program that issues the.
Although Rexx reached its peak in the mid 1990s, it is still worthwhile to learn. Taking the time to learn Rexx will give you a great introduction to programming and help you understand the basics of writing scripts. In addition, understanding Rexx will provide tools and foundation necessary to create mainframe server programs.
So lets get started with environment setup and an example of program that copies source file into destination file using POSIX API system calls to demonstrate open(), read() and write() system calls on Linux operating system.
A REXX program is called an exec. Before running an exec, you need to add the exec to your project, or download it from the mainframe, in the usual way. All REXX execs should start with a comment containing the character string REXX so that they can be distinguished from TSO CLISTs.
This web page attempts to fill a void for people wanting to create Rexx execs that will execute on any platform or Rexx implementation. It is geared toward the intermediate-advanced Rexx programmer and assumes some knowledge of the language. As you are probably aware, you can write general purpose Rexx execs which will execute anywhere with little or no changes.
