Use the && operator for and, and use the operator to do the or part. So your statement looks like this:

if A && (b || c)
  stuff
end

Do not use & and | for those tests, as && and are designed to work explicitly and optimally in if statements. They allow the tests to be short-circuited, so that if the entire test is known to be true or false, the remainder of the tests are not performed, thus saving CPU cycles.
