Hi!

If I do :-

nFlags = Bitor(8,2)

I get 10.

If I want to take the value of 8 out of the nFlags value, apart from simply substracting its value, how do I do this with one of the bitwise functions? Obviously, this is a simple example but I have a running nFlags value and if any of the flag conditions become obsolete, I want to remove (subtract) the obsolete value from the running flags total, preferably without having to test that the flag total even includes the value in need of subtraction. In other words, if I want to take the value of 8 from an nFlags value of 10, the nFlags value is corrected (to 2). However, if the value has already been removed and nFlags already == 2, then the action of trying to remove a value (ie., 8) that has already been removed from nFlags is processed, while still leaving the nFlags at 2 (because it had already been reduced).

I hope you understand that!

Thanks.
