Too simple, I basically understand it all. Personally, I think it's not useful.

Thank you, very useful~!~!

Even more basic. I've just started to get in touch with batch processing. :(

Top the second post... has the effect of attracting medicine... thanks a lot

Learning! Thanks to the thread starter!

Very worthy of learning!

The first post is still understandable, but the second one isn't.

There are only two posts on this floor, which is still too few. I hope to add some more in the future, with explanations and examples.

Great, learning it now

First, I'll top it and then come back to read.

Learn. . . . . .

It would be better if it could be more detailed.

The choice command can be used to let the user enter a character to run different commands. When using it, the /c: parameter should be added. After c:, the characters that can be entered should be written without spaces in between. Its return code is 1234...

For example: choice /c:dme defrag,mem,end
Will display
defrag,mem,end?

For example, the content of test.bat is as follows:
@echo off
choice /c:dme defrag,mem,end
if errorlevel 3 goto defrag should judge the highest error code first
if errorlevel 2 goto mem
if errotlevel 1 goto end

:defrag
c:\dos\defrag
goto end

:mem
mem
goto end

:end
echo good bye

Why can't the choice command be executed under CMD on my WINXP???

Let me take a look

There's so much to learn...
