hi, I would solve it by writing my own sort function: sortfoo = (StringJoin @@ # & /@ (Sort /@ IntegerDigits /@ ToExpression /@ StringSplit[#, " "] /. n_Integer :> ToString[n]) // Sort) /. {x_String, y_String} :> x <> " " <> y &; here is a tester function: With[{foo = ToString[RandomInteger[{100, 999}]] <> " " <> ToString[RandomInteger[{100, 999}]]}, {foo -> sortfoo[foo]}] regards, christoph On 02/07/2010 08:54, S.
