Actually, no. I think Lang's programs were the first ones to provide this
feature.
For example, in Psion Chess for PC (1985), there is a function called "Next
Best". By calling it repeatedly, you get all the best moves, sorted in
descending score order.
That's what multivariation does. However multivariation does this at every ply
depth, when Next Best does it only at the targetted depth. But in principle the
two features are very close.
