In AREV3.111 we use TAME to remove the CPU usage by an idle machine.



In OI I am trying to make a similar thing.



I either would like to have a routine start a program on a regular basis.  



OR 



I have created a program that loops until a set amount of time, problem with this approach is the CPU is being eaten up, is there anyway to make this work better.

In the editor, from the Exec box, enter the command



run declare_fcns "DLL_KERNEL32"



* Then in your program you can 



DECLARE SUBROUTINE DONTASKTHEEMU

DONTASKTHEEMU(200)



* You may alter the value to suit your hardware.



* This sheds CPU load by returning timeslice control 

* to Windows to process its own event queue (and other tasks, 

* threads and events like keystrokes and screen refreshes 

* and mouse moving).





Or else you can use YIELD() - see pg. 503 of the OI Programmer's reference manual.
