In this example (basically from the manual - I've added an (exit)):
(map set '(myin bcout) (pipe))
(process "bc" bcin bcout)
(set 'sum "123456789012345 * 123456789012345")
(write-buffer myout (string sum "n"))
(set 'answer (read-line myin))
(println (string sum " = " answer))
(exit)
'bc' is still running, I think. How should I be stopping it?
Could you send it a quit command?

yes, that works and stops the creation of orphaned processes with "S" status, I suppose. Thanks.
I've got processes with "Z" status too - Zombies?. These must have been caused by something else I've been doing recently (trying out all the OS commands...) :-)
While on the subject of processes, what's the best way to write and run a newLISP program that runs continuously, like the ntpd or launchd daemon, and does a task every minute or so? Rather than call a one-shot script from 'cron' or something.
Perhaps a different question. I want to write a script that runs in the background all the time I'm logged in. I've got two approaches to a continuous loop. Which is the better:
(do-stuff)
(sleep 10000))
(do-stuff)
(timer 'ticker 10.0))
(ticker)
Is it best launched one of the command-line options?
