   Note:
   The text PLEASE TYPE IN A NAME may not necessarily appear at the bottom of the screen (as shown above) but on another line, depending on the position of the message line as set by the Natural administrator.

8. In the first position of the input field next to PLEASE ENTER NAME:, enter any character and press ENTER.

   The test is terminated and the map editing screen appears.

12. Enter the command P0 as shown below:

    Rule ________________________________ Field #001 > P0 > + Rank 5 S 5 L 1 Struct Mode ALL ....+....10...+....+....+....30...+....+....+....50...+....+....+....70.. 0010 * 0020 IF & = ' ' REINPUT 'PLEASE TYPE IN A NAME' 0030 MARK *& 0040 END-IF 0050 * 0060 0070 0080 0090 0100 0110 0120 0130 0140 0150 0160 0170 0180 Enter-PF1---PF2---PF3---PF4---PF5---PF6---PF7---PF8---PF9---PF10--PF11--PF12--- Help Mset Exit Test -- - + Full Sc= Let
