实验一 DEBUG的使用实验内容：

　　　1、利用DEBUG程序中的“E”命令，将两个多字节数“12345678H”和“FEDCBA98H”分别送入起始地址为DS:0200H和DS:0204H两个单元中。

　　　2、分别用直接寻址方式和寄存器间接寻址方式编写程序段，实现将DS:0200H单元和DS:0204H单元中的数据相加，并将运算结果存放在DS:0208H单元中。-The experiment a DEBUG use experimental contents: 1, the use of DEBUG program of the "E" the order, will be more than two bytes "12345678 h" and "FEDCBA98H" respectively into the starting address for DS: 0200 h and DS: 0204 h two unit. 2, respectively with direct addressing mode and register indirect addressing mode write a program section, realize the DS: 0200 h unit and DS: 0204 h in a unit of data additive, and will be the result of the operation in DS: 0208 h unit.
