I've always put the %SHTDN at the bottom of my processing loop (a read loop or a sleep loop). Do what needs done and then IF %SHTDN, exit loop.
So with the signal method, if the program is sleeping and a signal is sent, does it wake it up out of the sleep? Can you point me to a decent site to show how to create and activate a signal program? This sounds like something I would like to understand.

Because with %SHTDN, you have to poll for the condition... i.e. check %SHTDN every second or two to see if an end request was sent. This is what I mean by "clunky"
With a signal, it calls your designated routine the moment the signal is sent, so you can respond immediately, no need for polling.

used %SHTDN so your reference to it being "clunky" made me go HUH?
