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

  Curses Screen Management function that initializes the
  terminal-type data and all screen functions.  You must call initscr
  before using any of the Curses functions or macros.

  Syntax:

       #include <curses.h>

       void initscr(void);
