OObject REXX API samples

Three API samples are currently included in the OBJREXX\API directory.
Each sample is installed into a separate directory.
Make files, which are compatible with nmake, are included in each sample directory
so that you can rebuild the samples.
In order to use the make files to build the samples, you must set up the environment
variables INCLUDE and LIB.

Compilation:
The environment variable INCLUDE must contain the path to REXX.H as well as the compiler
include path. This header file is included in the \OBJREXX\API directory.

Linking:
The environment variable LIB must contain the path to REXX.LIB and REXXAPI.LIB as well
as the compiler library path. These library files are included in the \OBJREXX\API directory.

Samples:
--------

callrxwn   - Windows mode application

           - Provides a sample call to the REXX interpreter, passing
             in an environment name, a file name, and a single argument
             string. A dialog box is created for the output.

           - Note that you must define a REXX standard input and
             output exit handler for a Windows mode application.
             This is not necessary for Console mode applications, however.


callrxnt   - Console mode application

           - Has similar functionality to callrxwn

           - Console mode applications calling Object REXX do not
             require input and output exit handlers.

rexxexit   - Console mode application that runs on Windows NT only.

           - Provides a sample call to the REXX interpreter, passing
             in arguments from the command line. A REXX input and
             output exit handler is also demonstrated. This is the
             source code for rexxc.exe.
