From applicable formations.
Square Thru n To A Wave;
  do the anything call; 
  Step & Fold.
Ends in various formations.
Notes:
- 
The anything call can be an 8-dancer call.
 - 
If the anything call is 'Lock' do a Lockit; if the
    anything call is 'Top' do a Fan The Top.
 - 
In our opinion, the caller should always use the complete name
    for the anything call: a dancer who has learned
    Catch anything n but has not been exposed to
    Catch Top n would not necessarily know that 'Top' refers
    to a Fan the Top (as opposed to a Spin The Top,
    Relay The Top,
    Tag The Top, 
     or some other call).
 - 
The anything call may end in a Diamond.  If so, do a Step &
    Fold from a Diamond: Centers 1/2 Press Ahead as Points Fold to
    end in a T-Bone 2 x 2.
 
    
Split Catch anything n [C3A]:
 Split Square Thru n To A Wave;
  do the anything call; 
  Step & Fold.
