OK, I give up. I think I might have gone insane. I believe that the
following
code worked on Friday, but now I run it, and it does not work! I'm
trying
to make a deffunction out of a test that I seem to be doing alot
(ccc3-is-b-or-c)
in a bunch of rules. I've commented out the original test in the
orgain-tonnage
rule (that did work), and put it into a defunction. The problem is that
after I (assert (tRec (CCC "M7C"))), the rule does not activate, because
it does not call the defunction. It looks right to me, and like I said,
I swear
it worked on Friday. I made the change to Funcall.java that Ernest sent
out
yesterday, but I didn't think that would make a difference... I did back
out the
change to see if it did affect something somehow, but nope, no
difference.
I'm not that proficient in CLIPS, so it is slow going for me when trying
to
do more advanced things. I could just repeat the test code in each
rule,
but I was hoping I understood the defunction stuff.
Anyway, a hint would be greatly appreciated.
