additionally, if its a must run singleton, you can aloc the dataq in the run up to your program and when you send any start command, if the dataq is aloc excl then you can run, if you cant get the lock its already running.

I've done this by using the data queue API's.
In the main loop of your program, do a rcvdtaq with no wait. If you get the *STOP message, you handle the request and make a graceful exit. You'd also need a means to put a message on the data queues. I wrote a quick little command to do so. Obviously, you need to create a data queue for the app.

Hello Paul,

I would suggest to handle a *STOP message Received by the server program... and write a small program to send the *STOP message
If you're back at your regular computer (for better typing), may I kindly ask for more details?
Are you talking of UNIX like signals? If yes, reacting to SIGTERM would be more appropriate. On Linux, if there's no explicit handler, the program ends in a sane manner. Okay, more sane than a SIGKILL, that is. :-)
