Question regarding loops and CAR: #:G18223 is not a list

Ah, that did the trick, or so it seems.

As for why I still "solve"ing, you're right, of course - I was working 
on this originally to NOT have to specify all of the parameters, but 
ALGSYS couldn't solve the system, so, it's just a legacy of the 
process.

Thanks again - interesting lesson in terms of how maxima does scoping, 
as I would have thought that s would be redefined each time I entered 
the loop.
