recordz(+Key, ?Value)

Records the term Value at the end of key Key in the indexed database.
Key
An atom, compound term, or handle.
Value
Any prolog term.

Description

Used to record any prolog term Value at the end of the indexed database entry associated with the key Key. A synonym for record/2. In the case of compound terms, all keys of the same name and arity are treated as equal.

If backtracking occurs through the call of recordz/2 the associated Value is not removed from the indexed database.

Modes and Determinism

Modules

This predicate is sensitive to its module context (tool predicate, see @/2).

(5) type error
Key is neither an atom nor a compound term.

    yes.
    [eclipse]: recorded(whiskey,Value).
