推荐答案

代码可能是这样的:

The code could be something like this:

@echo off
set /p var=Choose a option ('s' to start, 'q' to quit):
if %var%==q goto:eof
echo working!

在此示例中，如果您输入"q"，则正在工作！"将不会打印，因为您转到了脚本的末尾.您还可以将功能与批处理文件(！)一起使用.请查看我最近的答案:

In this sample, if you enter ''q'', "working!" will not be printed, because you go to the end of the script. You also can use functions with batch files (!). Please see my recent answer:
Batch variable equations[^].

Chances are, your code already works correctly; but you probably you haven''t started command interpreted, so it was not closed, but the console of you batch was closed. If you started it with CMD.EXE and then started your batch from the command line. Or, alternatively, start it with "CMD /K your_script_batch". Again, please see the help created by the script I referenced in my previous answer.
