我正在制作批处理文件编码器。用户逐字符输入密码，然后输出是该字符的简单代码。当我运行这个时，我收到的是每一个“真实”回显到输出。请帮忙！

批处理文件不会停止在标签上处理，它们只是移动到下一行并继续处理，因此程序将处理匹配％num1％的第一个字符上的goto，跳转到该标签并运行到程序的末尾。
因此，在每个标签中，您需要添加goto :eof，它将跳转到文件的末尾。如果你这样做，你将只处理％num1％的匹配，因为它将跳转到匹配的标签，然后跳到文件的末尾，退出程序。
您可以使用goto替换if语句中的call来解决此问题。这将在标签处运行代码，当代码跳转到文件末尾时，它将在调用后返回到行。
最后，您需要在if块的末尾添加goto :eof，以防止批处理文件在每个标签语句中运行。
类似于（显示一小段代码）
if %num6%==y call :true155
if %num6%==z call :true156
pause > nul

虽然其他答案说明了你的程序的直接问题，但我无法抗拒对它进行一些观察的诱惑。您应该研究批处理文件功能并尝试使用它们来编写更好（更简单，更快）的程序。在所有编程语言中都是如此，特别是在批处理文件中;否则你会编写基本和粗略的程序，这些程序当然不是批处理文件的好例子。例如：
1-您应该意识到，如果您检查六个输入字符中的每一个并执行具有相同转换的的六个不同部分，那么这将浪费代码！您可以只编写一次转换集，然后在六个不同的部分中使用它。这个概念被称为“子程序”。
2-一般来说，如果你多次编写相同的代码段而只是改变一小部分，那么你就不会使用编程语言的功能来实现这一点。您可以编写代码的“常规格式”，并在必须更改的部分中放置“参数”，然后让编程语言在一系列值上自动更改该参数。这是一个“循环”，在批处理文件中实现它的方法是通过FOR命令。
3-编程语言中最重要的概念之一是数组，它允许您在一个元素上指定某个操作，然后以相同的方式在一系列元素上重复该操作只需更改索引即可。如果在FOR循环中组合一个数组，则可以在几行代码中实现大而复杂的计算。
是的，我知道这些方法通常是通过经验获得的;但是，我只是想把它们呈现给你，这样你才能意识到它们存在。下面有一个批处理文件，它使用这些方法来实现原始程序的相同结果，但是要小得多。

没有返回goto语句可以返回并继续处理，因此只会处理第一个goto，然后通过以下所有内容进行处理。
以下示例将执行您正在尝试的内容，但代码和错误检查更少：

set "Input="
