List of Operators

General

Operator	- Description
Type	- Get the ProcessTypeID of a ProcessType.

Maths

Operator	- Description
+	- Addition.
-	- Deduction
*	- Multiplication.
/	- Division.

Logic

Operator	- Description
||	- OR. One or the other or both.
&&	- AND. Both.
^^	- XOR. One or the other, but not both.
!	- NOT.

Bitwise

(Logical operation per bit.)

Operator	- Description
|	- BOR. One or the other or both.
&	- BAND. Both.
^	- BXOR. One or the other, but not both.
~	- BNOT.

Memory

Operator	- Description
&	- OFFSET. Get the memory address of a variable. See pointer.
*	- POINTER. Get the value of the variable a pointer is pointing to. See pointer.

Example

Program operators;
Global
    int int_1 = 1;
    int int_3 = 3;
    int int_4 = 4;
    int someint = -5;
    String somestring = "AAP";
    String anotherstring = "BEER";
    byte somebyte = 6;
    signed byte sbyte = -2;
    byte b_5 = 5;
    byte b_12 = 12;
Begin

    say("---------- maths");

    say(int_3 + int_4);
    say(int_3 * int_4 + 1);

    say("---------- strings with numerical datatypes");

    say(somestring + anotherstring);
    say(somestring + ": " + int_3);
    say(anotherstring + ": " + int_3*sbyte);

    say("---------- mixed numberical types and typecasting");

    say(somebyte+someint);
    say((signed byte)someint);
    say((unsigned byte)someint);

    say("---------- logic");

    say(int_1&&int_4);
    say(int_4==int_3+int_1);
    say(!(somestring==anotherstring));

    say("---------- bitwise");

    say(b_5|b_12);  // 00000101
                    // 00001100
                    // -------- |
                    // 00001101 = 13

    say(b_5&b_12);  // 00000101
                    // 00001100
                    // -------- &
                    // 00000100 = 4

    say(b_5^b_12);  // 00000101
                    // 00001100
                    // -------- ^
                    // 00001001 = 9

    say(~b_12);     // 00001100
                    // -------- ~
                    // 11110011 = 243

    Repeat
        frame;
    Until(key(_esc))

End

Used in example: say()

This will result in something like:
