I also find J's silence upon startup a bit disconcerting. Maybe because its
prompt is just whitespace? Anyway, I have a utility called printPrompt,
which prints out welcome message consisting of the J version, timestamp, and
a random entry from the Phrasebook, e.g.
New J (v602a) session started on 2011-02-15 at 09:18:18
m7 =: 3&A. NB. Rotate last three to the left
The version and timestamp come in handy when I have multiple J sessions
going, or a multi-day session, or when I save an IJX log and revisit it
later. The random phrase keeps it interesting, and sometimes will teach me
something cool, or remind me of an tool I've neglected.
In general, the prompt is a positive indication that J is ready to talk to
me. I call printPrompt'' at the very end of my profile.ijs .
