From what I understand, you are not allowed to have the Code or Cipher Book in the Lodge at all, but can posses one for personal use. I also feel a Code/Cipher Book, or Monitor should not be in the hands of a candidate, unless there is a word he cannot understand, and the instructor uses it to teach from. I thought it was not allowed, but in the last few months, I have met with others who instruct, and they have said they will let a candidate have their Monitor to study from. My instructor said NO! I learned the questions and answers from Mouth to Ear, and feel that is what is proper. The Code/Cipher Book is a good way to stay sharp on the work if you (like me) don't have anyone close to study with, and stay on top of it. You have to know the work in order to read the code. My 2 cents, and you can kep the change...
