Need answers from people who know assembly language.

[+Random Terrain]

I'm about half way through correcting HTML errors on my web site and I noticed that Lesson 6 and Lesson 7 by Robert M still don't have answers for the exercises.

 

Can somebody who knows assembly language post the answers to the exercises?

Lesson 6

1.Given the following bytes (A) and bitmask (B) values calculate the result C, for C = A & B, C = A | B, and C = A ^ B.

1. A = %11111111, B=%10101010
2. A = %00000000, B=%01010101
3. A = %11110000, B=%01110111

1. %10101010, %11111111, %01010101
2. %00000000, %01010101, %01010101
3. %01110000, %11110111, %10000111

2.Given the following bytes (A) and bitmask (B) values calculate the result C, for C = A NAND B, C = A NOR B, and C = A XNOR B.

1. A = %10110110, B=%00000000
2. A = %11111111, B=%11111111

1. %11111111, %01001001, %01001001
2. %00000000, %00000000, %11111111

3.Fill in the blanks '_____' in this pseudocode example with what you believe is the correct logical function.

SUBROUTINE CheckPlayerStatus

BEGIN

        IF (PLAYER.has_green_key = TRUE) ___ (Player.is_touching_door) THEN

  Goto PlayerExitsLevel

        ELSE IF (Player.touching_monster = TRUE) ___ (Player.touching_arrow) THEN

  Goto PlayerKilled 

  ELSE IF (Player.touching_gold = TRUE) ___ (Monster.died) THEN

  Goto PlayerGetsPoints

        ENDIF

END CheckPlayerStatus

AND, OR, OR

(I would remove green from the key)
