Hi: I have the following example: "hELLO THERE!" Using Mathematica 8.0.4, how can I swap the lowercase and uppercase letters to output, "Hello there!" Thanks, Bill Hi, Bill, These two functions: revertCharacter[x_String] := If[UpperCaseQ[x], ToLowerCase[x], ToUpperCase[x]]; revertString[string_String]:=Map[revertCharacter,Characters[string]]//StringJoin; do the job in Mathematica 9 at least: revertString@"hELLO THERE!" revertString@"Hello there!" "Hello there!" "hELLO THERE!" I expect that it should also work in the version 8. Have fun, Alexei Alexei BOULBITCH, Dr., habil. IEE S.A.
