I found several other learning resources on J Software's Getting Started page.

They say to do this in the link Bill provided, but it's important to remember that a filename needs to be boxed before you can use it to import data in J. The first few times I tried file I/O, I had to re-discover that fact after an extended period of fussing. – estanford Jun 26 '10 at 10:57

Using the `files` library is usually the best workaround to avoid having to remember such nasty little requirements. – MPelletier Jul 20 '10 at 19:20
