Program - 5. Store the result in memory locations 4004H and 4005H with the most significant byte in memory location 4005H. The most significant eight bits of the two numbers to be added are in memory locations 4001H and 4003H.

HLT : Terminate program execution Add the 16-bit number in memory locations 4000H and 4001H to the 16-bit number in memory locations 4002H and 4003H. Dont leave outlines around your objects when you send them to cut (unless thats your desire effect).

That should make a dashed box appear and when you click on your work area the image should appear. Program - 4: Subtract two 8-bit numbers Sample problem: (4000H) = 51H (4001H) = 19H Result = 51H - 19H = 38H Source program: LXI H, 4000H : HL points 4000H MOV A, M : Get first operand INX H : HL points 4001H SUB M : Subtract second operand INX H : HL points 4002H MOV M, A : Store result at 4002H. Then switch over to your LXI program and then hold down the CTRL key and type V (paste command). Sample problem (4000H) = 14H (4001H) = 89H Result = 14H + 89H = 9DH Source program LXI H 4000H : HL points 4000H MOV A, M : Get first operand INX H : HL points 4001H ADD M : Add second operand INX H : HL points 4002H MOV M, A : Store result at 4002H HLT : Terminate program execution Subtract the contents of memory location 4001H from the memory location 2000H and place the result in memory location 4002H. Add the contents of memory locations 4000H and 4001H and place the result in memory location 4002H. STAX D : Store the contents of A register into memory location 4000H. MOV A, B : Copy the contents of B register into accumulator. MOV M, A : Store the contents of A register into memory location 2000H. LDAX D : Get the contents of memory location 4000H into A register. MOV B, M : Get the contents of memory location 2000H into B register. LXI D 4000H : Initialize DE register pair as a pointer to memory location 4000H. Program 1: MVI A, 52H : Store 32H in the accumulator STA 4000H : Copy accumulator contents at address 4000H HLT : Terminate program execution Program 2: LXI H : Load HL with 4000H MVI M : Store 32H in memory location pointed by HL register pair (4000H) HLT : Terminate program execution Exchange the contents of memory locations 2000H and 4000H Program 1: LDA 2000H : Get the contents of memory location 2000H into accumulator MOV B, A : Save the contents into B register LDA 4000H : Get the contents of memory location 4000Hinto accumulator STA 2000H : Store the contents of accumulator at address 2000H MOV A, B : Get the saved contents back into A register STA 4000H : Store the contents of accumulator at address 4000H Program 2: LXI H 2000H : Initialize HL register pair as a pointer to memory location 2000H. Store the data byte 32H into memory location 4000H.
