Boolean and logical operators

Question

I'm a begginer in Mozart-Oz, and I seek help because this language is not very intuitive, and lacks documentation.

I'm trying to apply this code (which works on eclipse when i write it in java) and doesn't work in oz, here are the details:

This is the code in Oz, it displays True (which is not logical since if A is true and B is false, A And B should be false)

declare
A=true
B=false
C=A And B
{Browse C}

This the code in Java, which displays False (It is the logical answer)

public static void main(String[] args) {
    boolean A=true;
    boolean B=false;
    boolean C=A && B;
    System.out.println(C);

}

@Kyle Spencer it acts like System.out.printLn(C), it displays on screen, and in my case it shows true once i compile the program — user3078046, Mar 30 '14 at 19:42

Solved it, apparently you have to treat And as a function not an operator. By using this syntax

{And true false} it will return false.

There is also an Operator: `andthen`. The semantics are slightly different. `andthen` does not evaluate its second argument if the first is False. – wmeyer Mar 31 '14 at 14:46
