Hi Ermine,

I'm not sure that I understand your question.  I think to achieve what 
you seem to be trying, you would simply write:

# printf "%d %s" 2 "abc";;

You just put the parameters in the order they came in the string.  Does 
that help, it seems like perhaps you needed more than that.

Regards,
Peter.
