I am quite unfamiliar with the concept of loop in J. what I meant about loop was the traditional "for loop" as in other languages, I even don't know if such a thing exists
I'd like to apply two path variables (one for reading and one for writing) and one other table (these 3 have the array size) in such a way that I can extract the elements one by one and do some computation till all the arrays taken care of. in other words I have 3 inputs for the verb (input path, output path, a table). could you give some hints how can I create such a verb (or loop)?
