Thanks HS!

That looks like a good move, if format will do the string 
conversion for me.

But one thing that would be troublesome is that i would have to 
make sure to count up the %s so that they match the number of 
arguments.  I would like to do without that, just like writeln 
does.

Anyhow, though, thanks for point out format.
