Binds - is there a way tio check range to target?

I was curious if there was a way to have a bind, or a script that a bind can run, that can check the range to a target...

Also.. if it is possible to have a bind, or a bind to a srcipt, that does an IF / THEN / ELSE type scenario?

Im hoping to make a Bind that will Check the range of the target, if the target is in range it will turn off a toggle and activate a power, if the target is not in raneg it will do nothing, or show a system / private message stating "You are out of range"

Sorry, no scripting like in WoW. Also, I don't know of any way to check the range of a target besides placing a waypoint on the map and gauging it that way. You can do a lot of things with binds, but nothing anywhere near that sophisticated. The developers have intentionally limited them to prevent botting and exploiting.
