I am trying to find out whether a series of integers y only contain a set of integers x
That is, 1 3 5 verb 5311 10531 536 1111111 should return 1 0 1 1 NB. only 1 3 5 occur in 5311 NB. not only 1 3 5 occur in 10531 NB. not only 1 3 5 occur in 536 NB. only 1 3 5 occur in 1111111 NB. x only contains digits 0-9 without repeat. #x is max 10 NB. leading zeros should be ignored in elements of y. No max for #y I have tried several methods using combinations of e. i. under< etc. but haven't yet found a succinct verb that achieves what I want. I hope my description is clear Help gratefully received! ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
