inverse boolean Navision

Question

Is there a more easy way to inverse a boolean instead of using a IF ELSE construction?
Normally I would use the ! infront of a boolean value. But that doesn't do the trick in Navision

Answer 1

You can use the NOT keyword in place of !.

Answer 2

You can use this example to invert a boolean variable Value:

PROCEDURE InvertValue(VAR Value @ Boolean;);
begin
  Value := NOT Value;
end;
