/* A test program to demonstrate the direct variable interface to ARexx.
 * Opens a public port called "VarTest" and then waits for REXX messages.
 * The port stays open until a "CLOSE" command is received.
 * Usage:  run vartest
 * Then send commands from within ARexx by "address 'VarTest' command"
 *
 *    This version for Manx. WGL
