[Jprogramming] J701 for IOS

['Mike Day' via Programming]

You're welcome.

I should have said that I often "cheat", as follows:

    for a smallish script,  assuming you've got email send/receive
    enabled on both
    devices,  copy-paste script on one device to an email, send to self,
    copy-paste from email to a J edit window.  Works fine from laptop to
    iPad.
    iPad to laptop not quite so good, as I usually end up with double
    line-spacing.
    Large scripts tend to be difficult to select and copy at the iPad end.

Also, item (0) below applies to the laptop, in my case.

Cheers,
Mike
