Hi
 I'm sorry, people doing logic have been using + and . a
lot longer than C has been using & and |. I specifically stated
what I would use. Look at most any pre-C math book and
you'll most likely see the + and . used for OR and AND.
 These are just symbols until one applies meaning to them. I
don't see the issue. One should be able to adapt to different
conventions because that is the way things will be represented
from different sources. I adapt and I hope others learn to
do it as well.
 I don't see the issue with using upper and lower case to
indicate normally close or normally open? What difference
does it make how one represents it?
