Solved.

Never do the following:

(defmd frgo () slot-1 :slot-1 (c-in 0))

then later on

(setf (^slot-1) (c-in 1)) ^^^^^^^^ Cells doesn't recognize this (well, how should it? - it can't) so we're ruining the Cells metadata ... (It has to be a normal setf without the c-in ...)

Hi Kenny, hi all ...

i've never had this before ... Or so I think ;-)

What may cause

`=0/ANONCELL/NIL]' is not of the expected type `REAL'

to happen ? It's like some cell is not recognized as such and doesn't get "evaluated" correctly? Or is it?

Thx for any pointers...

Frank
