! 8: \ THIS PROGRAM TESTS THE CORE WORDS OF AN ANS FORTH SYSTEM.
! 9: \ THE PROGRAM ASSUMES A TWO'S COMPLEMENT IMPLEMENTATION WHERE
! 10: \ THE RANGE OF SIGNED NUMBERS IS -2^(N-1) ... 2^(N-1)-1 AND
! 11: \ THE RANGE OF UNSIGNED NUMBERS IS 0 ... 2^(N)-1.
! 12: \ I HAVEN'T FIGURED OUT HOW TO TEST KEY, QUIT, ABORT, OR ABORT"...
! 13: \ I ALSO HAVEN'T THOUGHT OF A WAY TO TEST ENVIRONMENT?...
