1、若DS=1000H,BX=2000H,(12000H)=56H,(12001
若DS=1000H,BX=2000H,(12000H)=56H,(12001H)=78H,AX=1000H,执行“ADDAX,[BX]”指令后,AX=()。A8856HB6678HC8800HD6600H
2、分析下列程序段: BUF DW 2456H, 7816H, 5731H,
分析下列程序段:BUF DW 2456H, 7816H, 5731H, 896AHMOV BX, OFFSET BUFMOV AL,2XLATMOV CL, ALMOV AL,6XLATINT 3程序段执行后结果:CL=();AL=()
3、现有(DS)=2000H,(BX)=0100H,(SI)=0002H,(2
现有(DS)=2000H,(BX)=0100H,(SI)=0002H,(20100H)=12H,(20101H)=34H,(20102H)=56H,(20103H)=78H,(21200H)=2AH,(21201H)=4CH,(21202H)=B7H,(21203...

5、水准测量计算校核∑h=∑a―∑b和∑h=H终―H始,可分别校核()是否有误。
水准测量计算校核∑h=∑a―∑b和∑h=H终―H始,可分别校核()是否有误。A水准点高程、水准尺读数B水准点位置、记录C高程计算、高差计算D高差计算、高程计算
6、已知SP=25H,PC=4345H,(24H)=12H,(25H)=34H,
已知SP=25H,PC=4345H,(24H)=12H,(25H)=34H,(26H)=56H,当执行RET指令后,SP=(),PC=()。
