Thank you Neil. I was afraid that might be the case. At one point I was successful in compiling the function after turning it into a module similar to what you have shown but when I tried to compile it, there was an error that said that it was successfully compiled but that it would produce some error if I tried to run it outside of Mathematica. I gave up on trying to compile as a module at that point. I will check with tech support on the release date for V12 and if CWC and CWD will be include in the initial release or when they will be added. Thank you again.
