Its always worked for me.

You are leaving out the output format specifier in the first case Willard.  Go 
look up printf in any C reference book.  Also, the "foo bar" should point at 
the defined variables.  Either that or bit rot has gotten to your copy...

Normal syntax would be:

printf("list-of-format-strings\r", nameofvar, nameofvar, etc);

That's off the top of my head, but that's how I remember it, having written a 
bunch of stuff in C.
