I tend to use the tools I already use. So in this instance, I'd do it in two stages: 1. use Joel's 'tally function to count items: >> tally [1 2 2 3 4 5 5 5 6] == [[1 1] [2 2] [3 1] [4 1] [5 3] [6 1]] 2. remove anything with a count of 1 from the resulting series. I'll leave you to work out how to do stage 2 I got the tally function from here: http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-message.r?m=rmlKDDS Sunanda. -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
