I'm sorry, people doing logic have been using + and . a

you'll most likely see the + and . used for OR and AND.
What Genius decided that + should be OR, as opposed to AND, which seems
actually logical and not counter-intuitive?
In my logic, 'A' would indicated the normally
opened contact an 'a'
would be the normally closed contact for relay A. I'll use + to
indicate OR and . to indicate AND.
You already lost me. You may as well have used ! and $ instead of A and
a.
:)
P.S. C programming convention (which most people would relate to
immediately) says that next time you should use & for AND and | for OR. These are just symbols until one applies meaning to
them. I
Right, but it's hard to work around ingrained meanings that have been with
you since 1st grade.
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?
None, I just felt like pointing out that whoever decided to use the plus
sign for OR was most likely insane.
