11.3.187 recorda/3

Synopsis

recorda(+Key, +Term, -Ref)

records the Term in the internal database as the first 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

If Key is a compound term, then only its principal functor is significant. That is, foo(1) represents the same key as foo(n).

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

Exceptions

Key is not instantiated

uninstantiation_error
