如何使用MARIE编写堆栈组织程序

Question

我正在编写一个程序来评估下面的语句，但是我必须使用堆栈组织的计算机来完成它。这意味着只有pop和push才能访问内存。

使用此程序作为我程序的示例时​​，如何执行此操作？：

    Load    A           
    Store   Stack0      
    JnS Push        
    Load    B       
    Store   Stack0      
    JnS Push        
    JnS PopS        
    Load    C       
    Store   Stack0      
    JnS Push        
    Load    D       
    Store   Stack0      
    JnS Push        
    Load    E       
    Store   Stack0      
    JnS Push        
    JnS PopM        
    Load    F       
    Store   Stack0      
    JnS Push        
    JnS PopS        
    JnS PopM        
    JnS PopA        
    Load    G       
    Store   Stack0      
    JnS Push        
    Load    H       
    Store   Stack0      
    JnS Push        
    Load    K       
    Store   Stack0      
    JnS Push        
    JnS PopM        
    JnS PopA        
    JnS PopD        
    JnS Pop     
    Halt

任何帮助将不胜感激。我是MARIE的新手，到目前为止一直没有得到任何帮助。谢谢！ =）
