The API samples in the directories rexxapi1, rexxapi2, rexxapi3 demonstrate how to:

- Register external functions from within external functions
- How you can provide external functions (written in C) in a library that can
  be accessed from Open Object Rexx (after they have been registered)
- How data can be returned from external functions
- How the REXX Variable Pool Interface can be used to access and modify Open
  Object Rexx variables

rexxapi1
========
Start: "rexx apitest1.rex"
Description: This sample registers a few functions that produce some screen output or
             return some data

rexxapi2
========
Start: "rexx apitest2.rex"
Description: Sets the value of a variable by using the Rexx Variable Pool Interface


rexxapi3
========
Start: "rexx apitest3.rex"
Description: A more extensive use of the Rexx Variable Pool Interface


For more information about the Open Object Rexx API read rexxapi.pdf, "Chapter 2. 
Classic Rexx Application Programming Interfaces".
