「set/a在這個時候是意外的」

Question

我是新來的批次，主要用於這一個學校項目。我也是堆棧溢出的新手，所以我們將不勝感激。當我到達代碼中的「：MARK」時，我不斷收到錯誤消息「set/a unexpected was currently at this time」。我只想在這裏轉儲整個代碼，對不起，如果它很混亂。

再一次，對不起，如果我通過在這裏轉儲整個腳本做錯了。我只是不知道自己在做什麼。

Answer 1

你的錯誤的根本原因是這一行QUESTIONTEN：

set/p athree= 

這看起來像一個錯字你的意思是設置aten，而不是athree。

更具體地說，由於aten是空的，內MARK，比較最終被這樣解釋：

if ==3 set/a mark="[mark value]+1" 

注意，左操作數是空的。該行被解釋爲錯誤，這就是爲什麼你會收到錯誤。將athree更改爲aten可以解決此問題，但有一個技巧可以修復比較，以便在其中一個操作數爲空時不會中斷腳本。只要把東西放在雙方。例如，用引號括住比較器。

if "%leftoperand%"=="%rightoperand%" ... 

然後，即使其中一個或兩個都爲空，它也不會終止您的腳本。它看起來像if ""==""。

此外，調試批處理文件的一般技巧是通過在關鍵位置放置echo語句（即使是簡單的語句，如echo 1）來縮小發生錯誤的位置（以及爲什麼）。然後，當您在輸出中看到1時，您知道該行已執行，並且您的錯誤在該行之後。一旦發現腳本終止的壞行，您可以回顯腳本的副本以查看腳本將其解釋爲什麼，這將幫助您找出問題所在。

像這樣：

echo if %aten%==3 set/a mark="%mark%+1" 
if %aten%==3 set/a mark="%mark%+1" 

我希望幫助。
