Unfortunately I no longer have access to a DEC-10, and the DEC-10
Prolog sources are sitting on a tape that would be a hassle to restore, but
according to the manual and my recollection both read(X) and get(C)
advance the input appropriately and try to unify the object scanned
with their argument. If the unification fails, the advancing of the input
stream is not undone, but the calls fail.
