DLY PROC NEAR ；定义函数
PUSH CX ；cx入栈保存
PUSH DX ；dx入栈保存
MOV DX,10000 ；dx装入10000,也就是dx=10000
DL1:；标号,也就是一个记号
MOV CX,6801 ；将cx中存入6801
DL2:；标号
LOOP DL2 ；执行这条语句的时候,程序会现判断cx的值是不是0,如果是0就继续向下执行.如果不是0就将cx的值减一,然后跳转到DL2这个位置执行.然后一直循环,知道cx的值减到0为止.我们看到cx的初始值是6801.也就是要循环6801次.
DEC DX ；将dx的值减一
JNZ DL1 ；如果dx的值减一后不是0,就跳到DL1处执行,如果是0,就继续向下执行
POP DX ；将之前保存的dx值还原到dx
POP CX ；将之前保存的cx值还原到cx
RET ；返回主程序
DLY ENDP ；函数结束
说白了这个就是一个延时程序,它就是让cpu空转一段时间.
