How do i end a turn without giving orders?

i don't know for sure haven't played it for a very long time, but it thought after end turn without making an action, you get a message that you havent given an order.
Or maybe there's a skip turn?

edit;

i just bought the game, can't find a way to end turn without taking an action first.

In the Amiga version, there's no option to skip a turn.

In the PC DOS version, select PASS from the main menu to pass the turn.

... of course... pass
thanks for the answer
