Suppose I have two lists of similar length,
    p1={n[i],a[i]}
and
    p2 = {n[i],b[i]}
and I'd like to create a new list,
    p3 = { n[i], f[ a[i], b[i] ] }
if the new list comes from one parent list then it is relatively simple to
write and apply a transform w/ map like
    h[{x_,y_}]:={x,f[y]}
    newlist = h/@list or = Map[h,list]
but two parent lists confuse me

thanks again!
