Wow! Thanks Cliff. I don't understand it all yet, but it does exactly what I need. The capability to remove specific elements in a vector is something I have needed fairly often:
0-.~2 0 3 1 5 0 0 1 2 3 1 5 1 2 3-.~1 2 3 4 3 5 3 2 6 7 3 3 6 1 4 5 6 7 6 Where is this handy dyadic verb documented in the J doc?
