Hello Ed,

We can programmatically change the view zoom value with the VBA code:
ActiveWindow.ActivePane.View.Zoom.Percentage = 200

Based on my test, if I set the Zoom percentage value to 600, it will throw
an error:
"one of the values passed to this method or property is out of range"

Therefore, as Rick said, this is a "built-in limit for the zoom function".
Would you consider Jon's suggesion and let us know if that works for you?

Thanks
