          The quick-cluster output provides two simple tables, but no 
information that enables a user to ascribe a cluster group membership to 
individual cases within a data set.
          
          I presume the required data is implicit within the <number of cases 
in each cluster> table, but there appears to be no mechanism for accessing it.
          
          Any help or advice much appreciated.

     It seems to me that what you need is the /PRINT = CLUSTER option, which 
unfortunately PSPP doesn't have.
     
     I will send a message to the author of the K-Means cluster feature to see 
if he will add it for us.
     
I got a reply from the author.  He would like to help but, like the rest of us, 
he lacks the time.

If somebody else would like to code this and contribute it, they'd be very 
welcome.  I think this would
be a relatively straightforward job for someone who knows a little C 
programming, and would be a
gentle introduction to hacking on PSPP.
