Problem with And & or

une_tortue

Here is a program that comes from tutorial 9:

Loop
         Clear()

         j = controls( 0 )

         if !j.zl and !j.zr then
                Print( "Hurray!" )
          endif

           update()
repeat

With this program the 'and' operator acts as the 'or' operator and vice versa
is this normal ?

In the above it only displays "Hurray!" when zl is NOT pressed (! operator) AND zr is NOT pressed.

So if zr is pressed or zl is pressed (or both are pressed) it is not displayed
