/sys$common/syshlp/helplib.hlb CC, Run-time functions, mv[w]addstr  *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 add the specified string, to which str points, to the
  specified window.  The mvaddstr macro acts on the stdscr window.

  Syntax:

       #include <curses.h>

       int mvaddstr(int y, int x, char *str);
       int mvwaddstr(WINDOW *win, int y, int x, char *str);
