Thanks Eric. I'll take a stab at it. It will be instructive. But I may well be getting back.
To make my requirement more precise, I want to trigger some "handler" verb after a given interval, leaving J to carry on working normally, but to do it only once, not repeatedly. That's the only use I make of wd'timer' -- but I'm using it heavily, in essential places. Since J does not multi-task, I was talking nonsense about an "asynchronous" 6!:3. Nor will a bash script work on the Mac because with 2!:1 as well as 2!:0 J602 hangs until the shell process finishes. J701 JHS too. Try: 2!:1 'sleep 5' On Thu, Jan 5, 2012 at 4:46 PM, Eric Iverson <eric.b.iver...@gmail.com> wrote: > There is no JHS equivalent of wd'timer'.
