Hi, I need a verb to turn a list of numbers between zero and nine into a table where each item is 10$0 except at the place indexed by the input numbers, for example:
v 0 1 2 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 My approach using ammend leaves me puzzled: v=:1&(]})&(10$0) v 1 2 3 1 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 Here I have to bind two nouns (1 as x and 10$0 as y) to the verb (]}) but maybe that doesn't do what I think it does? The rank of v doesn't seem to matter, it gives the same output, but I know I want it to use 0-cells of the input list. I'd be happy to see what the idiomatic way to do this is, and maybe how to fix my approach. greetings, Lorenz ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
