    Greg,
     
    Sorry , I missed that.
     
    You know, personally, I don't use the "contrary" and "same" convention.
    Years of math by hand trained me to watch out for signs when
    adding and subtracting - got bitten too many times. The advantage is,
    of course, one doesn't have to remember special sign rules.
     
    My choice of letters was simple:
    N: negative as in L-D, P: positive as in L+D; Q: well, next after P :)
     
    Boy, what a compression of formulation, though - I am so happy about that!
