I have several BASIC processes that are quite CPU intensive which I would like to "slow" themselves down a bit so the don't take so much processor time. Is anyone aware of way for a UniVerse BASIC program to change it's own processing priority? Something akin to getpriority()/setpriority() is C?
Perry, Not sure of your platform but if you are on Unix/Linux then look at nice/renice. They key advantage is it becomes an OS solution, you don't have to manually tune your code with sleeps and pauses. If you renice to a higher value and your machine is doing nothing else, it will let your intensive process have all the cpu it needs but as soon as a process with a lower nice value requires cpu, your intensive process goes to the back of the queue. Tuning with sleeps seems like trying to re-invent the wheel when the kernel has its own scheduler. No idea if you are on windows sorry. A couple of gotchas... With nice the lower the value, the higher the priority so -19 is going to get everything it needs and +20 comes last. IIRC a standard foreground process like a telnet session defaults to 0. You can only renice any process below 0 to speed them up if you are the root user but IIRC you can renice all your own processes to slow them down.
