间接寻址是指不直接给出要访问单元的地址，而是将该单元的地址存在某些特殊存储单元中，这个用来存储地址的特殊存储单元称为指针，指针只能由V、L或AC（累加器）来承担。采用间接寻址方式在访问连续地址中的数据时很方便，使编程非常灵活。间接寻址存取数据一般有三个过程：建立指针、用指针存取数据和修改指针。

1）建立指针

建立指针用双字传送指令（MOVD），利用该指令将要访问单元的地址存入指针（用来存储地址的特殊存储单元）中。指针建立举例如下。

MOVD &VB200， AC1 //将存储单元VB200的地址存入累加器AC1中指令中操作数前的“&”为地址符号，“&VB200”表示VB200的地址（而不是VB200中存储的数据），“//”为注释符号，它后面的文字用来对指令进行注释说明，软件不会对其后面的内容进行编译。在建立指针时，指令中的第2个操作数的字长必是双字存储单元，如AC、VD、LD。

2）用指针存取数据

指针建立后，就可以利用指针来存取数据。举例如下。

MOVD &VB200，AC0 //建立指针，将存储单元VB200的地址存入累加器AC0中

MOVW *AC0， AC1 //以AC0中的地址（VB200的地址）作为首地址，将连续两个字节（一个字，即VB200、VB201）单元中的数据存入AC1中

MOVD*AC0， AC1 //以AC0中的地址（VB200的地址）作为首地址，将连续四个字节（双字，即VB200～VB203）单元中的数据存入AC1中
