This is a simple test program that can be compiled using fc and loaded
into the target system using the X command of the monitor.

     1- Copy the file main.x generated from compiling the monitor into
     this directory.  This provides links to monitor routines that are
     called for input and output.

     2- Set the code address to a valid RAM address in the file hello.

     3- Compile hello using the command   fc -lox hello

     4- Load the hello.ols file into the target system using the monitor.

     5- Execute the program by typing G XXXX , where XXXX is the starting
        address set in step 2.
