VMS Help CC, Run-time functions, mv[w]insstr  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Curses Screen Management macros that move the cursor to coordinates
  (y,x) and insert a string on the specified window.  The mvinsstr
  macro acts on the stdscr window.

  Syntax:

       #include <curses.h>

       int mvinsstr(int y, int x, char *str);
       int mvwinsstr(WINDOW *win, int y, int x, char *str);
