[amibroker] Re: Synchronize zoom levels with static variables and ZoomToRange

["treliff" <treliff@xxxxxxxxx>]

Thanks very much, Herman, that gives me something to chew on! I'm in 
awe of folks with programming skills that get so much out of the 
program.

And I am sure willing to put some of my own effort in but allow me to 
reach back should the need arise.

On a side note I am surprised that this feature (synchronizing Zoom 
Ranges in different windows) is, if not a standard feature, then at 
least something other users must wished and/or developed before me.
