Global Variables
                             ----------------

    The function  INITVERN() sets  up the following  global variables
    for  use by several of  the functions contained  in this library.
    THESE  VARIABLES MUST BE SET UP PROPERLY OR ELSE YOUR APPLICATION
    WILL NOT OPERATE AS EXPECTED!

    For  the most  part  you need  not  concern yourself  with  these
    variables,  just know  that  they exist  and  you will  be  fine.
    AGAIN: INITVERN() takes care of setting all these up for you.
