Called changes: I must keep track of at least two other bells: the bell I am following, and also the bell that bell is following

There are two ways to call changes:

  1. Down: the call a to b means
    1. a is two places above b
    2. a will move to be immediately above b, and the bell formerly above b will now be above a.
  2. Up: the call a to b means
    1. a is one places below b
    2. a will move to be immediately above b, and the bell formerly above b will now be above a.

By convention WRS calls down, not up.

y (if z isn't at lead
z (if a isn't at lead
a
b
→ c  me
d (if c isn't at back

This is for calling down.

Kinds of calls Who c will follow Who they will follow
b called away
b to c or b to z 		c follows a c must now figure out who a is following
either z or at lead
a called away
a to y 		c follows b (still) c must now figure out who b is following
d called to b
d to b 		c follows d d follows b
d called to a
d to a 		c follows b (still) b follows d

In retrospect I see I have missed a couple of kinds of calls.
