IFFSnooper generates a text interpretation of the data in the BHAV edit window, just as in the main BHAV window. The value p0 = 6 defines the motive as Comfort.
Changing this value to 7 defines the motive as Hunger.
The same thing happens to the motive definition in line 20 if we copy in the data from line 13 and then set p0 = 7.
