Ceder Square Dance System (CSDS) ==> Sequences

Parsing bug? #2

A minor parsing issue -- seems like either

something useful should be done, or
a barf should occur.

Instead, no dancers change positions at all, and nothing happens.

---- Sequence ----
Heads Pair Off,
Touch 1/4,
Zig Zag Zig Zag

It's true that the call isn't legal from this position. A gripe would be nice, though I understand that code clutter to catch cases like these won't be a priority...

The program executed the calls properly.

CSDS allows more than one call to be given on a single line.

On line 3, it executed the call 'Zig-Zag' followed by the call 'Zig-Zag'. Executing Zig-Zag twice from a R-H Box ends all dancers in the same position!
