testAddCommandHandler.rex
A Rexx demonstration program to show how to add and use a Rexx command handler implemented in Java.

The companion Java program (implementing the Rexx command handler) is: RedirectingCommandHandler.java. Among other things it defines the commands

and demonstrates how to create failure and error conditions in the command handler if no or an unknown command gets issued by the Rexx program.

To run enter the following command on the command line:
