Hi all, If I have x=: 0 10 20 30 y=: 5 6 7 12 13 21 22 23 28 How would I get to 3 2 4 A result showing the number of items of y between items of x No item of y will equal an item of x. I'm currently using a loop to set up intervals between items of x and then using +/(interval e. y) to get the number of matches on each iteration; this is producing the result however having problem working out how to do it more efficiently. Thanks John
