List of Operators
General
| Operator | - Description | 
| Type | - Get the ProcessTypeID of a ProcessType or define a new datatype. See Type. | 
| . (period) |  - Element access. <struct>.<element>. In case of a struct array, if no arrayelement is specified, it points to [0] (see example).
 | 
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 access to the variable a pointer is pointing to. See pointer. | 
Example
Type _point
    int x;
    int y;
End

    int int_1 = 1;

    setXY(&myPoint);
    Repeat
        frame;
    Until(key(_ESC))
End
Function int setXY(_point* p)
Begin
    p.x = 3; // this is actually (*p).x = 3, but . can be used like this
    p.y = 5; // this is actually (*p).y = 5, but . can be used like this
    return 0;
End
Used in example: say(), key(), Global, Type, Struct, Array, Pointer, period
This will result in something like:
