OR: Logical OR: The OR instruction carries out the OR operation in the similar way as described in case of the AND operation. The restriction on source and destination operands are also the similar as in case of AND operation. The instance are as follows:Example :
1. OR AX, 0098H2. OR R AX, BX3. OR R AX, [5000H]4. OR [5000H], 0008HThe contents of AX are considering 3FOFH, then the first example instruction will be carried out as given below.
So the result 3F9FH will be stored in the AX register.
Assume that the registers are initialized to EAX=12345h,EBX =9528h ECX=1275h,EDX=3001h sub AH,AH sub DH,DH mov DL,AL mov CL,3 shl DX,CL shl AX,1 add DX,AX
what will be the value of EAX after following instructions execute? mov bx, 0FFFFh and bx, 6Bh
