Sorry, we went so late last night I completely forgot about this. I'll keep trying to find time (and keep sending me emails so I remember to). I will try to dig thru the below.

Do I gather there is a new error now about CACHE? I do not even recognize that. After a full recompile I get another error: Error: Attempt to take the value of the unbound variable `CACHE'.

Note: Not cache? but cache ...

Digging into the 3c code reveals:

The cell rule gets stored as a string. This is done in #'3c? :

(defmacro 3c? (rule&key test ephemeral observer) `(call-3c? '(lambda (node cache cache?) ;;<<<<<<<<------ This is the "offending" LoC ... (declare (ignorable cache cache?)) (let ((*calc-nodes* (cons node *calc-nodes*))) ,rule)) ;;<<<<<<<<<------ There cache is not defined anymore - see below for explanation ... :test ,test :observer ,observer :ephemeral ,ephemeral))

When running #'test-prep I get the following last lines in a trace:

0> 3c?-rule: got rule "(lambda (triple-cells::node triple-cells::cache triple-cells::cache?) (declare (ignorable triple-cells::cache triple-cells::cache?)) (let ((triple-cells::*calc-nodes* (cons triple-cells::node triple-cells::*calc-nodes*))) (let ((h (3c (3c-find-id \"dell\") !hw:happen))) (trc \"rule sees happen\" h) (cond ((string-equal h \"arrive\") \"home\") ((string-equal h \"leave\") \"away\") (triple-cells::cache? cache) (t \"away\")))))"

I can't see what is wrong with this...

cache needs the explicit package as well: (cond ((string-equal h \"arrive\") \"home\") ((string-equal h \"leave\") \"away\") (triple-cells::cache? triple-cells::cache) ;;<-- need package on both (t \"away\")))))" HTH, ken
