I want to be able to read and write files, etc. How can I do this?

A:
Check out Chapter 28: Data Files of Learning J.
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.

Using the `files` library is usually the best workaround to avoid having to remember such nasty little requirements.
