Amelia: I am glad you got it to work. I know how difficult it is to get this kind of thing, especially if you are coming from another paradigm. I do agree that if you have to emulate a while not end of file loop in J, you are going to run into problems. The analog of your assignment in J would be to read the values from a file (people often produce external data by hand or from programs in CSV files). If you were doing this using arrays in C, you would have to specify a maximum number of inputs (30 in your case), size your arrays accordingly, and keep track of how many items you actually used. In J, you would not have to specify the array size, nor keep track of how many inputs there were, and your code would be exactly the same if there were 3 or 3000000 inputs. In the J community, this is seen as an advantage.
