public class RexxParser {

        Options options = new Options();

        CommandLineParser parser = new DefaultParser();
        CommandLine cmd = null;
        try {

            System.exit(1);
        }

        if (cmd.hasOption("r")) {
            String rexxCode = cmd.getOptionValue("r");
            System.out.println("Parsed REXX code: " + rexxCode);
        } else {
            System.out.println("No REXX code provided.");
        }
    }
}

java RexxParser -r "ADD 1 2"

Parsed REXX code: ADD 1 2
