Solution1:

Lable   Mnemonic    Comments

Start:  MOV  A,B ; move data of B to A

            MOV C,B ; move data of B to C

            MOV D,B ; move data of B to D

            MOV E,B ; move data of B to E

            MOV H,B ; move data of B to H

            MOV L,B ; move data of B to L

Stop:   HLT

Solution 2:

Lable   Mnemonic    Comments

Start:  MOV  A,B ; move data of B to A

            MOV C,A ; move data of A to C

            MOV D,C ; move data of C to D

            MOV E,D ; move data of D to E

            MOV H,E ; move data of E to H

            MOV L,H ; move data of H to L

Stop:   HLT

P2. Write an ALP to load data 33H to Registers A, B and C.

Solution 1:

Lable   Mnemonic    Comments

Start:  MVI  A,33H ; move data 33H to A

            MVI  B,33H ; move data 33H to B

            MVI  C,33H ; move data 33H to C

Stop:   HLT

Solution 2: 

Lable   Mnemonic    Comments

Start:  MVI  A,33H ; move data 33H to A

            MOV  B,A ; move data of A to B

            MOV  C,A ; move data of A to C

Stop:   HLT
