The iPad’s help window doesn’t seem to include a delete feature. je only gets a file up for editing, while jd only lists files, as far as I can see. I found that 1!:0 gives a unix ls-type listing, which is useful. So I thought 1!:55 might work for deleting scripts, etc. However, it returns a domain error.
Thanks for any help, Mike ps Jprogramming is probably the wrong forum - sorry if so. Please reply to [email protected].
