Question

我目前正在研究MARIE SIMULATOR，我试图得到三个输入的小数，并将它们全部加在一起。我将我的代码保存为.mas并尝试组装它。它说我有1个错误，但汇编列表完全是空的！我发现当我从中移除Jump OP时，代码会组装并运行，但是，我需要Jump来获得正确的答案。无论我到哪里，我都会看到跳跃，因为我已经写好了，所以我不知道自己是不是错了，如果我的模拟人员被错误或是什么。

ORG 100     /Starting point // Gustavo Brandao. No Partners
    Input       /Request user input for first number
    Store   NumA    /Store the number
    Output      /Display number to screen
    Input       /Request user for a second number
    Store   NumB    /Store number
    Output      /Display number
    Input       /Request user for third number
    Store   NumC    /Show number
    Output      /Display number
Loop,   Load    NumA    /Load the first number, will also loop from here
    Add Sum /Add with zero and location which will save the sum
    Store   Sum /Store the sum
    Load    NumB    /Load the second number for the skip condition control
    Subt    One /decrement the number
    Store   NumB    /Store the number. when 0, code will skip the jump
    Skipcond 000    /Skip when the second number reaches zero
    Jump    Loop    /Used to repeat addition until second number reaches zero
    Load    Sum
    Store   NumA    /Storing sum in NumA slot to make code easier to read
Loop,   Load    NumA    /Loading the previous sum
    Add FSum    /Adding previous sum to zero and final sum location
    Store   FSum    /Storing final sum
    Load    NumC    /Second skip condition control
    Subt    One /decrememting number
    Store   NumC    /Storing skip condition
    Skipcond 000    /When the third inputed number is zero, loop will end
    Jump    Loop    /Loops back to second part of code
    Load    FSum    /load the final sum for output
    Output      /Display final sum
    HALT
NumA,   Dec 0   /First number; Will be overwritten with input
NumB,   Dec 0   /Second number
NumC,   Dec 0   /Third number
Sum,    Dec 0   /Stores the sum for the first multiplication process
FSum,   Dec 0   /Stores sum for the second multiplication process
One,    Dec 1   /Used to decrement values

Answer 1

所以我意识到我不能在程序中有两个“循环”，因为它不会识别要跳转到哪个。我将第二个命名为Loop2并且它有效。我得到了错误的答案，但没有任何一点调整不会解决

我的MARIE Sim Jump功能无法正常工作
