Square Thru BUT
Starting Formation: Facing Couples (or R-H Wave).
Ending Formation: Dependent upon call

Definition: Square Thru the given number, stopping in a Wave; do
the given call.

Note: It is my belief that the given call is done from the Wave,
not from Facing Couples. For example, "Square Thru but on the 4th
hand Recycle". That means that it's more precise to say "Square
Thru but on the 3rd hand Hinge" instead of "Touch 1/4".
