I think you can accomplish this with AGGREGATE, under the DATA menu [it
creates a new .SAV file with freqs, sums, avgs, etc of your data by id].  I
think the function you want is NCASES.  In the new file, you can select by
whatever criteria you need.
Good luck,

variables.  Though these ID's are unique, each may occur 1, 2, or 3 times
within the database.  How would I select out only ID numbers which occur
three times within the data set?
