AZ0 - The Main Menu. Select the program you desire and enter the number of your choice when it is requested. The selected program will then be loaded from the default disc drive or directory, if it is not already loaded, and executed. For information about each program, select the HELP function. If the selected program fails to load, check your selection or return to the operating system (DOS) and check to make certain the AZ programs are on the default disc or directory (i.e. execute a 'DIR' command). The AZ programs must be on the default disc or in the default directory. Check your operating system manual for more information.
