What you really need is the ability to POKE. So you execute the phantom and return it's handle to another process (PID) The waiter stops at a regular INPUT. The responder then could POKE something carriage return to the waiter's INPUT That would be instant reaction, no wait, and no false starting.
Did it on OA on Sequoia because they had a POKE. -----Original Message----- From: Doug Farmer <dfar...@epicor.com> To: 'U2 Users List' <u2-users@listserver.u2ug.org> Sent: Thu, Dec 27, 2012 1:56 pm Subject: [U2] Sleeping in Basic Happy holidays all, I just want to make sure I did not miss something over the U2 releases. 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.
