OK, that sounds good, but why doesn't this work ?
if(ADPMIN > 0.0);spacefill ADPMIN;else;spacefill 25%;endif;
I wanted ellipsoids by default, reverting to 25% if anisotropic Uij's are
not defined. But "show ADPMIN" says it's not defined in any case. (And I
wonder what happens if ADPMIN is negative?)
