[Oberon] Size of LONGINT in ETHOberon

[Dieter]

According to NW the size of LONGINT is +/- 2147483647


However when I run

==================================================

MODULE powerof2;
IMPORT Out;
PROCEDURE power*;
VAR i : INTEGER; value : LONGINT;
BEGIN
i := 0; value := 1;
WHILE i < 32 DO
Out.Ln(); Out.Int(i,5); Out.Int(value,20);
INC(i); value := 2 * value;
END;
END power;
BEGIN
END powerof2.power

===================================================

I get
