What is the definition of list_node? Obviously it's a structure that has fields
named data and next, but that's a little short.

My guess is that you have to translate a linked list of nodes into a sequence of
nodes. Then you'd only need to do this:

function sum_list_(integer sum,integer index,sequence nodes)
if index<=length(nodes) then
    return sum_list_(sum+nodes[index][DATA],index+1,nodes)
else
    return sum
end if
end function

function sum_list(sequence nodes)
return sum_list_(0,1,nodes)
end function

Not the most efficient, but the closest to a verbatim translation.
