    This function is the proper method of terminating a program in DOS
    versions 2.0 and above. It closes all files, and hands control back to
    the parent process (usually COMMAND.COM), along with the return code
    specified in AL.
 
       Notes:         The return code may be tested by means of Function
                      4Dh or the DOS ERRORLEVEL command.
