You normally get no output AFAIR using c++ type compiled programs with printf or cout -- and perhaps an error set in cout, but I can't remember about that now.

But don't forget, D uses DMC's runtime, not Visual Studio.  Make sure you are comparing to DMC compiled programs.

writeln works, just not writefln so much. Haven't tried eg. writeln( format( "%s", value ) );

Can have a version system for with, and with out the terminal. Just don't think I need to do more than just adding and removing the .def file from the compiler arguments.
