|                                    |
|          This program is an example of how the C arrays of            |
|       structures generated by Screen Machine can be displayed.     |
|                                                                       |
|          Note:                                                        |
|          Screen Machine always generates the structure "_scrn".  If   |
|          you are including more than one screen generated by Screen   |
|          Machine in a given program, only one declaration of the      |
|          "_scrn" structure should be copied into the program.         |
|                                                                       |
|                                                                       |
