Bill, Thanks. I did get the compilation to work, after dropping the .h from the iostream.h fstream.h and iomanip.h include directives and adding 'using namespace std;'. In addition, on Daniel's suggestion I added '#include <algorithm>' to a couple of files with the sort function, but I look forward to the new version.
