Sorry, Eric, but could you explain the provenance of iOS 7? - is this
something on iphones or in Windows or Mac or whatever? - in other
words, who needs to worry?
Thanks,
Mike

A user has reported that iOS 7 exposes a bug in J (at least I assume
it is a bug in J rather than iOS, but there is a tiny chance some
future iOS update will fix the problem).
The problem is the keyboard is disabled in 'stacked input state'.
E.g., if you type sentence f=: 3 : 0 and then keyboard return, J is in
a state that accepts input lines until the closing right paren, but
for some reason the keyboard is disabled so you are stuck.
There are 2 workarounds:
Using the J return button (immediately to the right of the input area)
instead of the keyboard return button (for an unknown reason) keeps
the keyboard enabled when entering stacked input state. This allows
you to enter sentences for the definition and then provide the closing
right paren. Curiously this colors the return button blue and
subsequent inputs color it the expected green.
Second workaround is to avoid stacked input state and instead enter
the definition in a temporary ijs file in the E window. This involves
a few extra steps but in general can be more efficient as you can
easily edit the definition.
If stuck with the keyboard disabled you can kill the J task, but a
cleaner recovery is to get the closing right paren entered another
way. If you have a closing right paren on a line in the session you
can recall it to the input line and enter it with the green return. Or
you can switch to Notes app, enter and copy a right paren and then
switch back to J and paste it and press the green return.
