There are two batch files: a.bat and b.bat. In b.bat, call a.bat. Now I want that if an exception occurs in a.bat when calling a.bat, it won't return to b.bat. I don't know how to implement this.

Determine based on the abnormal return value in a.bat:
if level XXX=xxx exit
if level XXX=xxx exit

It can be done.
exit can only terminate a.bat, but it still needs to return to b.bat to continue executing b.bat. What I mean is if a.bat has an exception, it will no longer return to b.bat. The whole program terminates, that is, once a.bat has an exception, nothing is executed. Don't forget that the whole program executes b.bat, and in b.bat, call a.bat

根据用户提供的内容，直接翻译的话是：
Terminate a.bat according to the return value
goto :eof
不过需要注意原句中“根据返回值来终止a.bat”翻译为“Terminate a.bat according to the return value”，“goto :eof”保持原样。所以整体翻译后就是：
Terminate a.bat according to the return value
goto :eof
Terminate a.bat according to the return value
goto :eof

Still don't understand my question. When a.bat is abnormal, I need not only to end a.bat but also to end b.bat. b.bat also doesn't execute anymore. goto:eof will only end a.bat, but I still need to return to b.bat to continue executing the remaining program.

LZ didn't understand the meaning of user pkone on the 2nd floor:
There is usually an exception return value when an exception occurs in a.bat. In b.bat, use if level XXX=xxx exit to judge the exception return value and end the operation

Actually, strictly speaking, it's not an exception. It's a branch of the program. If the branch is executed, it ends all programs.

Try adding the following statement to b.bat:
call a.bat || goto :eof

This doesn't seem to work, right?
call a.bat || goto :eof
This sentence seems to mean that if call a.bat fails, then execute goto :eof
But in fact, it's not that call a.bat fails
call a.bat || goto :eof
This sentence seems to mean that if call a.bat fails, then execute goto :eof

In b.bat, there is "call a.bat". I make a judgment in the a.bat script. If the status is "fail", output "Abnormal" to the log. At the same time, end both a.bat and b.bat. Now, a.bat ends but b.bat still has to execute until the program finishes.

I really don't understand what you mean. What can be done with two bats can be done with one bat, and they can be combined. P.S.: What does "log" refer to?

I also don't understand it very well. This is a test code for whether 1.bat Call 2.bat runs normally : )
You can try renaming 2.bat (deliberately creating an error). At this time, 1.bat will know that an error occurred when 2.bat was running and output relevant information...
Brother sunyao can refer to the principle...
Running environment: Windows CMD Shell
1.bat
2.bat

:: Judge whether the called 2.Bat runs successfully. As long as there is a preset errorlevel return value, it runs successfully!
if %errorlevel%==1000 ( echo 2.Bat executed successfully! ) else ( echo 2.Bat failed to run! )
