/sys$common/syshlp/helplib.hlb CC, Run-time functions, mv[w]getch  *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), get a character from the terminal screen, and echo it on the
  specified window.  The mvgetch macro works on the stdscr window.

  Syntax:

       #include <curses.h>

       int mvgetch(int y, int x);
       int mvwgetch(WINDOW *win, int y, int x);
