Some of the � undocumented features� are really bugs. One example: TANK at G16, ANTI-TANK at H1, FLAG at H2, and TANK MOVER from H16 to H3 (direction = up). If the TANK enters the TANK MOVER at H15, H13, H11, H9, H7, H5, or H3, the player will get message, � You Won ! ! !� However, if the TANK enters the TANK MOVER at H16, H14, H12, H10, H8, H6, or H4, the TANK will be hit at H9, H8, H7, H6, H5, H4, or H3, respectively. It is a bug, not � undocumented feature� because of the inconsistency. When the program manages the events (TANK movement, ANTI-TANK awareness of its enemy and it's shooting, the LASER movement, and the hit), there is improper order of the events. (TANK movement and LASER movement are supposed to be in parallel, not by turns, although they are taking turns on display.)
