18. The MOV Instruction

• MOV instruction is a copy instruction.

• MOV copies the source operand to the destination operand without affecting the source.

      ; Immediate value moves
              mov     ax, 7       ; Immediate to register
              mov     mem, 7      ; Immediate to memory direct
              mov     mem[bx], 7  ; Immediate to memory indirect 
  
      ; Register moves
              mov     mem, ax     ; Register to memory direct
              mov     mem[bx], ax ; Register to memory indirect
              mov     ax, bx      ; Register to register
              mov     ds, ax      ; General register to segment register
  
      ; Direct memory moves
              mov     ax, mem     ; Memory direct to register
              mov     ds, mem     ; Memory to segment register
  
      ; Indirect memory moves
              mov     ax, mem[bx] ; Memory indirect to register
              mov     ds, mem[bx] ; Memory indirect to segment register
  
      ; Segment register moves
              mov     mem, ds     ; Segment register to memory
              mov     mem[bx], ds ; Segment register to memory indirect
              mov     ax, ds      ; Segment register to general register
