That was my first thought too but I looked at the schematic and the IO
is pulled up by a single resistor on the other side of the bit switches.
It is indeed a typo in what I assume is Andreas' code:
MODULE Oberon0; (*Oberon-0 command interpreter / AP 15.5.20 Extended
IF SYSTEM.BIT(swi, 0) THEN RS232.Send(ORD("0")) ELSE
RS232.Send(ORD("1")) END ;
