Forgive the question, but my experience is only with the original APL and not APL2. I have a (general array) vector. Each element is a string vector. For example:
x←'abcd' 'efg' 'hijkl' Now, if I have: y←'hijkl' z←'hhh' How can I tell if y is in x? How can I tell if z is in x? I can easily do this with a loop, but that's not APL. This is as far as I've gotten: x∘.=y (I am one function away from completing a keyed files system for GNU APL!) Thanks! Blake
