Mikael,
I was updating the Elements of FlashForth document (after a long
pause) and was checking to see what would happen as I filled up the
parameter stack to the maximum of 26 elements for FF5 on a PIC18. I get
to the 20th element and the behaviour surprises me. I had expected to be
able to accumulate 26 elements because of the line
#define PARAMETER_STACK_SIZE d'52' ; 26 cells parameter stack
in p18f-main.cfg.

Is this a bug? Should there be a message to say that the stack has
overflowed along with the "?" ?
