Thanks, BOAC. Perhaps the NG is similar to the 747-400
Looking at the final LEGS page of a company route for a 747-400, you might see something like this (if a STAR or descent constraint has not been programmed).
_____ACT RTE 1 LEGS___ 9/9
ANOBO (38NM) .857/FL380 (small font)
RYN.....(108NM) - - -/- - - - -
VTBS....(77NM) - - -/- - - - -

The FMC doesn't put .875/FL380 at the last two waypoints. It seems to be sensing that these are close to the destination (and perhaps has generated a simple descent profile)
