No, I just want an easy display of typeout. The interruption of
keyboard entry you describe was in J6 and I was OK with it.
Right now, I'm trying to get beginning programmers to see what happens
when events occur. They have written websocket handlers, and I want
them to be able to put typeout in them to see what happens. The problem
is that when they type out, it takes away the prompt, and the line
containing the prompt.
Working like J6 did would be fine here.

As a general rule, typing interactively when event handlers are going
off is problematic.
Imagine, for example, that you were typing something arbitrary, like:
A quick brown fox jumps over the lazy dog.
Now, imagine that an event handler goes off ever place a . is inserted:
A q.uick .bro.wn. f.ox ju.mps o.ve.r t.he. lazy. dog.
It's going to be a mess no matter what you do,
But this can be worked around by using a different approach.
For example, on unix, you can use tail -f filename to display
everything that gets appended to a file. With that, and a separate
window, you can use fappend in J to have event handler messages show
up without messing up your interactive display. (On windows, I guess
you'd have to install cygwin to get the tail command)
Would something like that work for you?
Thanks,
