How is the NOT instruction broken, because it returns negative number?
technically its supposed to: AMOS stores numbers as 32 bit signed numbers
so when you do a logical NOT operation it will set the signed bit:

eg.  then number 8 in 32 bit binary is 00000000000000000000000000001000
     when it is NOT'd     it becomes   11111111111111111111111111110111

notice the last bit(the sign bit) is set so it will become a negative
number which you will notice is -9, which is what the NOT instruction
will return
