terpri

   /ter'pree/ TERminate PRInt line.  [{LISP 1.5} and later,
   {MacLISP}] To output a {newline}.  Still used in {Common
   LISP}.  On some early {operating systems} and hardware, no
   characters would be printed until a complete line was formed,
   so this operation terminated the line and emitted the output.
