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!"



Hi, Bill,

These two functions:

revertCharacter[x_String] :=
If[UpperCaseQ[x], ToLowerCase[x], ToUpperCase[x]];


do the job in Mathematica 9 at least:

revertString@"hELLO THERE!"
revertString@"Hello there!"

"Hello there!"


I expect that it should also work in the version 8.

Have fun, Alexei
