1.MOVCL,20H[BX][SI]；结果(CL)=(DS:[BXSI20H])=(091DH:0056H)=(09226H)=0F6H2.MOV[BP][DI],CX]；结果是将CX的值5678H存入内存(SS:[BPDI])=(1E4AH:0056H)=(1E4F6H)中，即结果是(1E4F6H)=5678H3.LEABX,20H[BX][SI])；结果是将内存偏移地址[BXSI20H]=0056H送给BX，即结果(BX)=0056HMOVAX,2[BX]；结果是(AX)=(DS:[BX2])=(091DH:0058H)=(09228H)=1E40H4.LDSSI,[BX][DI]；结果是将内存双字单元(DS:[BXDI])=(091DH:0056H)=(09226H)中的内容分别送给SI和DS,即结果为(SI)=00F6H,(DS)=1E40HMOV[SI],BX；结果是将BX值0024H送给内存单元(DS:[SI])=(1E40H:00F6H)=(1E4F6H)中即最终结果为(1E4F6H)=0024H5.XCHGCX,32H[BX]；结果是将CX的值5678H和内存单元(DS:[BX32H])=(091DH:0056)=(09226H)中的内容00F6H互换，互换后结果为(CX)=00F6H,(09226H)=5678HXCHG20H[BX][SI],AX；结果是将AX的值1234H与内存单元(DS:[BXSI20H])=(091DH:0056H)=(09226H)中的内容5678H互换，互换后结果为(AX)=5678H,(09226H)=1234H
