Well, this is very old info, it's documented and there is a reason for it. If
you supply invalid parameters to the function it will behave erratically. In
other words: Garbage in, garbage out. If your program calls a function with
invalid parameters, it is your program, that is buggy, not the called
function.
I agree that it would be better to have the functions check the parameters,
but it was a deliberate decision to leave parameter checking off to save code
and make it run faster. I don't use this strategy on larger machines, but when
fighting for each byte, I think it's ok.

Uz
