Good to hear!

Others have told you how to do this using XOR.

I'd like to point out that Ada often has better ways to accomplish
things that are done with bit-fiddling in other languages. So if you
can explain why you need to invert those bits, we might be able to
give you a better way to accomplish the same thing.

For example, specifying the exact position of bits in registers is
much simpler in Ada than in C.
