LC3地址簿錯誤

Question

試圖讓這個代碼來運行它是LC3地址簿，但我不斷收到以下錯誤：

線21：指令引用標籤「書」不能在9位表示簽署PC偏移

第22行：指令引用標籤「當前」不能在9位有符號PC表示偏移

線67：指令引用標籤「當前」不能在9位表示簽名PC偏移量

行69：指令引用標籤「當前」不能在9位有符號PC表示偏移

線77：指令引用標籤「當前」不能在9位有符號PC表示偏移

線79：指令引用標籤「當前」不能在9位有符號PC表示偏移

線90：指令引用標籤「PROMPT5」不能在9位有符號PC表示偏移

代碼在這裏 - >http://pastebin.com/8nZk3Dfd

任何幫助表示讚賞，發現在線代碼，但要使其工作。

Answer 1

你得到這些錯誤的原因是因爲你有更多的字符串後的變量。請記住，.STRINGZ中的每個字符都會佔用一塊內存，並且當您的變量距離想要使用它們的代碼太遠時，您會得到PC偏移錯誤。

如果您在字符串提示之前移動變量，那麼這些錯誤應該消失。

Answer 2

這裏有一些錯誤修復了，你的程序現在將組裝並至少打印所有的字符串，但是我將把修復運行時錯誤留給你。
