Hi Linda,

When I run that sentence I get a different result:

    (]j.1:)^:<10
10 10j1 10j2 10j3 10j4 10j5 10j6 10j7 10j8 10j9

A slightly different case:

    (]j.1:)^:(<10) 5
5 5j1 5j2 5j3 5j4 5j5 5j6 5j7 5j8 5j9

Vocabulary for ^: monadic says:  u^:(<m) <--> u^:(i.m) y

Does that help?

Cheers, bob
