I can't answer your specific question.  However, I would suggest 
using -collin- and/or -coldiag2- instead.  I know that when i was 
trying to replicate results from elsewhere, I had better luck with 
those programs than I did with -coldiag-.  I believe there was an 
error in the formulas for -coldiag- that John Hendrickx fixed in
-coldiag2-.
