Thanks Marshall. I'll need to chew on these for a little, but they are just what I was looking for.

You could also set test=: ,&.> test . This one doesn't have to go through I. to get the indices, so it is preferred.

I have a bunch of strings where each string is boxed and each word in the string is also boxed. The problem is to replace any word that contains a number with a generic string i.e. "NUMBER". For example, if the input phrases are: test=: (<;:'dogs and cats'),(<;:'3 blind mice'),(<<'alpha'),(<;:'6 plus 100'),(<;:'robot model r2d2') The output should be: output=: (<;:'dogs and cats'),(<;:'NUMBER blind mice'),(<<'alpha'),(<;:'NUMBER plus NUMBER'),(<;:'robot model NUMBER') I can get the indices of the words to be replaced pretty easily, but I can't figure out how to use these indices to amend the original phrases. ]indices=: I.@; L:1 (+./)@('0123456789'&e.)
