As you are seeing from the responses, there are usually many different ways
to code a solution, some more efficient than others. It is always a good
idea to NOT simplify your examples as you apparently have done in your
question... there is no way to know what the most efficient solution is if
we do not know what you actually have to work with. I mean, if your posted
question was exactly what you really needed, then even this might could be
the correct answer for you...

=MID("ABxy",2*(B1-10)+1,2)
