I would be careful of believing NAP :) The sleeping is, I believe, based entirely on the time slicing and clock interrupting ability, and so dependent on that mechanism internally of the underlying O/S.
I have found, on various implementations, that NAP doesn't actually support any possible delay, but only quantized results. Try looping for 1000 iterations on NAP 1 and then spewing TIME() and you'll see. -----Original Message----- From: Doug Farmer <dfar...@epicor.com> To: 'U2 Users List' <u2-users@listserver.u2ug.org> Sent: Thu, Dec 27, 2012 2:47 pm Subject: Re: [U2] Sleeping in Basic Thanks for this tip on NAP, The documentation does say it sleeps for milliseconds. I tried it and it works. RQM for UniData says it does the same as sleep. Well 1/2 of the problem solved! Still looking or a UniData answer.

Since the Microdata Reality days, I have used "SLEEP nn" to sleep for nn seconds. Simple, usually does the trick. But in today's gotta have it now, I won't wait, environment, a second is sometimes way too long. Is there anything I missed over the last few years to sleep for less than a second? I am executing a phantom command from a UniObjects subroutine call and waiting for it to finish. I am using a phantom, just in case the program aborts or hangs. I am not in control of what code is being run, it could try to read or write to an unopened file for example. If the program does hang, I get the dreaded "Error 30102" message (not helpful at all). In most cases, the program reads the data it needs and finishes in less than a second. The UniObjects subroutine then writes a flag I can pick up to see that the data is ready to return to the UniObjects client. I don't want the subroutine constantly looping and reading for the flag. This would take a lot of the CPU cycles. But, I don't want to wait up to a second to see that the phantom has completed. Any ideas would be helpful. This needs to run on both UniData and UniVerse. Have a great New Year. One more year older for us "experienced" developers in the PICK community.
