Marc, your reference was helpful.
Jos=:(1 }. ] |.~ [: <: [)^:(1 < [: # ])^:_ [: i. ]
Josephus2 =: 4 :'(|x&+)/i.->:y'
The 4 indicates a dyad function only:
Jos 12
10
Josephus2 12
|domain error: Josephus2
| Josephus2 12
Jos allows a monadic result, but I have no idea of its meaning. Josephus
does not allow a monadic use.
Thanks. Linda

I'm not sure I understand your question-you defined Josephus2 as a dyadic
verb.
':' is the explicit definition conjunction (m : n). Where the left argument
'm' is 4, a dyadic verb is produced; 'n' is the body of the verb. (See

Best,
Marc
