turn off echo/print

Hello,

I'm very new to Igor so this is probably a really easy problem. How do I stop Igor printing results to the History window?
I have a function which uses WaveStats and I would like it that when WaveStats is called nothing is printed to the History Window. That
is the function executes silently.

Thanks

Calls wavestats without printing to history or complaining if there are errors
