EVEN
                                      ====

           Two functions to test whether a long int is EVEN or ODD


Usage:
------

        evenness% = EVEN(lint)

        Returns compliment of lint's bit #0, ie TRUE if lint is even


        oddness% = ODD(lint)

        Returns compliment of lint's bit #0, ie TRUE if lint is odd


This toolkit comes in two versions: EVEN and EVENi. The core code is
identical, but EVENi employs no library functions and is therefore more
compact if used on its own.
