does not already refer to a variable.

taken. The @code{b_getval/2} predicate generates errors if @var{Name} is not
an atom or the requested variable does not exist.
Notice that for compatibility with other systems @var{Name} @emph{must} be already associated with a term: otherwise the system will generate an error.
