Calls listed at A2 are the standard A2 calls, corresponding to the Callerlab A2 list.

Calls listed at A2V are variations of those calls, or calls that are used at that level but are not explicitly on the list.

For example, A2V currently contains:

• (Pass & Roll) But (anything)
• (The Windmill) (dir) But (anything)
• All 8 Swing & Mix
• Grand Remake

A1V contains:

• (Cast A Shadow) Don't Spread
• Couple Of 3 CONCEPT
• Ignore (anyone) For (anything)
• Replace (any) With (any) CONCEPT
• Start (A) CONCEPT

For example, at A1, I believe callers might want to say 'Some work as a couple of 3, all 1/4 Thru'. The A1V concept 'Couple of 3' allows this.

CSDS requires that each and every call, concept, identifier, numeric, modifier, etc. be on a list.

You can display what is on a list from the CSDS main menu via List | View a Level.
