1.11+\ THIS PROGRAM TESTS THE CORE WORDS OF AN ANS FORTH SYSTEM.
1.12+\ THE PROGRAM ASSUMES A TWO'S COMPLEMENT IMPLEMENTATION WHERE
1.13+\ THE RANGE OF SIGNED NUMBERS IS -2^(N-1) ... 2^(N-1)-1 AND
1.14+\ THE RANGE OF UNSIGNED NUMBERS IS 0 ... 2^(N)-1.
1.15+\ I HAVEN'T FIGURED OUT HOW TO TEST KEY, QUIT, ABORT, OR ABORT"...
1.16+\ I ALSO HAVEN'T THOUGHT OF A WAY TO TEST ENVIRONMENT?...
