11.3.189 recordz/3

Synopsis

recordz(+Key, +Term, -Ref)

records the Term in the internal database as the last item for the principal functor of Key; a database reference to the newly-recorded term is returned in Ref.

Arguments

Key

term, must be nonvar

Term

term

Ref

Description

Any uninstantiated variables in the Term will be replaced by brand new, unattributed variables (see ref-sem-sec).

Exceptions
