Hi Mike, 
Both versions gave me the same error message. Am I missing something? 

Here's the code I tried: ....

I pasted to MSWLogo, removed np and rp from your code, ran perfectly.

Problem solved I think. I notice that you have changed 
the definition of np to:

to np 
make "coord.stack [] 
make "penf 0 
localmake "coord.posn (list  xcor ycor heading) 
ifelse pendownp [make "coord.posn fput 1 :coord.posn]~ 
                [make "coord.posn fput 0 :coord.posn] 
push "coord.stack :coord.posn 
end

coord.stack has to be initialised when MSWLogo is loaded otherwise it won't 
operate as a stack.

make "coord.stack [] has to be run outside of np

Regards Mike
