Thanks!

I appreciate the advice.  In this case, the dataset is rather large  
(i.e., with numbers of observations in the 50-75k range), and all I  
need is to repeatedly sort the observations WRT their distance from  
specific records taken from another dataset.  The -cluster measures-  
command seemed well suited to this (I'm not too concerned about speed  
here), but I'd of course welcome other suggestions.
