How does the flight data processing computer handle direct VOR
routing between VORs it doesn't recognize? Does it barf on that
too, or is this barfing specific to VOR radial-distance?


It will barf on that too. It can't process to a VOR/radial/distance fix if
it does not recognize the VOR the fix is based on. It'd be like asking you
to drive 50 miles due east of a town that does not appear on your road map.
