Greetings, and sorry about the basic question.If I have a mixed array, i.e.:m←5 5⍴⍳25m[2;2]←'X'What I am looking for is the correct way to tell which elements are character and which are numeric.I know I can do:m∊⎕AVThat gives me exactly what I am looking for. It just seems like a lot of work for each element of m to get compared with each element of ⎕AV. DialogAPL defines monadic ∊ to give this, but IBM APL2 uses it for something else. I just thought there might be an efficient idiom for this in IBM APL2.Thanks.Blake
