Dear Paolo,
Right! I was bit by this at first. After I found the correspondence
between the coefficients in the Int'l Tables and the GSAS names, I must
have typed them in 3 or 4 times before realizing I needed to update the
file with the "U" option before leaving that screen.
Your message has cleared up much of my confusion. Thanks for your help.
