[comp.ai] demons: was FRL first ?

Hi everybody,

can somebody tell me if FRL was the first language to introduce the
if-needed, require, if-added and if-remove demons ?
In KRL, I only know of To-establish which is equivalent to if-needed.

Thanks in advance,

     Conniver, circa 1972 (McDermott, MIT) contained a database with similar
daemon mechanisms.  The Conniver manual appears as an ancient MIT AI lab memo.
