Do the anything call, omitting the final Extend or Step Thru.
  Optionally, the caller could say Hold The Line | Wave to mean the same thing.
Some callers use the phrase To A Line instead of To A Wave
  if the (designated) dancers are to stop in a Line.  For example, from Columns:
  Checkmate The Column, 
  Last Two To A Line.
Here is a partial list of calls (C2 or below) that might be done To A Wave:
|

| Scoot Back (Centers) To A Wave: 
 |   |  |   |  | before Scoot Back
 (Centers) To A Wave
 |  | after (Note that the Outside dancers
 are not offset, but have adjusted

Square Chain Thru To A Wave [C1]:
 From Facing Couples (or R-H Wave).
  Square Thru but on the 2nd hand Left Swing Thru 1 & 1/2.
  Ends in a L-H Wave.

The following calls (C2 or below) contain the phrase 'To A Wave' but are
  not part of this concept:
