Wayne, You cannot read in a set. If you read in the result of print, you get '(set 1 2 3), which is a list beginning with the symbol 'set, not a set. Sets are a derived datatype using structs, not a primitive on recognized by read and write. You can use the functions serialize and deserialize to store sets, if you need to.
