printnlprocedure
  • in - ITEM ... - virtually any scheme object and any number of ITEMs. These are printed to the terminal via display with a space between ITEMs and newline after the last ITEM is printed. (printnl = print + nl, or newline.)
  • in - prn: <output-port> - by default, printnl (and all other print/write... procedures) print to current-output-port. However, the prn: keyword option directs printing to any open output port.
  • returns: no value.
