R: [Linrad] Re: Setting priorities in Windows

Hi all.

For set set the priority you can use a BATch file to initiate the 


CMD /C START/{priority} {path to program}

Where {path to 
program} is the fully qualified path to the program you wish to start and

{priority} is one of Realtime, High, AboveNormal, Normal, BelowNormal, Low

There is also opportunity to see another param ( start /? ) or see also http:
