From applicable formations.
All or Center 4 do the anything call.  Outside 6 move up one position as in 
  Swing & Circle 1/4.
The move up direction for the Outside 6 (clockwise
  or counter-clockwise) depends upon the facing direction of
  the dancer who becomes the end of the Center 4 after the anything call.
  After completion of & Circle 1/4,
  the Outside 4 adjust as necessary to become Couples facing in.
  Repeat the entire movement (including the anything call) for each 1/4
  (e.g., if the fraction is 3/4, do the entire movement 3 times).  
  If no fraction is given, do the entire movement 4 times.
Notes:
- 
Swing & Circle fraction [C1] 
    is the same as Swing-Slip & Circle fraction.
- 
The ending formation for the Center 4 could be a Line, a Diamond
    or any other applicable 4-dancer formation.  For example, from a 1/4
    Diamond formation (a Diamond between In-facing Couples) the
    caller could call a Diamond Circulate & Circle 1/4.
- 
The move up direction for the Outsides can change for each 1/4
    fraction of the call.  For example, from a R-H 1/4 Tag: Mix & Circle 1/2
    would be a Centers Mix (ending in a
    L-H Wave); Outside 6 move Counter-Clockwise one position;
    Centers Mix (ending in a R-H Wave); Outside 6 move Clockwise
    one position.  Since this usage of & Circle fraction
    is awkward to dance, callers usually only use it as an occasional gimmick.
- 
Since the anything call can be done either by all 8
    dancers or by just the Center 4 dancers, the caller should be
    explicit as to who is to do the anything call.  For
    example, on a U-Turn Back & Circle 1/4
    does everyone U-Turn Back or just the Center 4?  Perhaps
    anything & Circle fraction
    should be defined as Center 4 do the anything call unless the
    anything call requires interaction with the outside dancers?
CONTRAST THE FOLLOWING:
- 
  Mix & Circle 1/2:
  - Centers Mix; Outside 6 move up; Centers Mix; Outside 6 move up.
 
- 
  Mix & Circle 1/4 & Circle 1/4:
  - Centers Mix; Outside 6 move up; Outside 6 move up.
