There are side effects. For example, it will discard the half-width exclamation mark in the variable value. Other side effects haven't been observed for the time being, and it remains to be discovered by you all.

Does it have a scope of action? If it is defined inside a for () loop, does it only work within the for () loop? If so, it can reduce some possible side effects.

The meaning of setlocal is to localize variables. When it encounters the first endlocal statement, it ends this localization process. So, if defined inside for (), if the endlocal statement is not added in the appropriate position, the setlocal enabledelayedexpansion statement will always take effect.

In addition, more than 32 levels of setlocal statements will generate the error "The maximum setlocal recursion level has been reached". And one of the means to solve this problem is to use the endlocal statement to end the variable localization process before executing the 33rd setlocal statement.

It's very detailed. I kind of understand. Thank you~~~

I also hope I can, but it's just that I have more heart than strength (don't get me wrong~~heh)
Too busy! When I have time, I can only rest!
In fact, there are many experts in the forum. You can benefit a lot by asking any of them casually!
I will definitely write again when I have time! Actually, I'm also a noob!! Haha!

These past two days I've been worrying about the command setlocal EnableDelayedExpansion, but today I saw your post and suddenly saw the light, thanks a lot.

Well done! Hope the thread starter posts more to let us newbies learn. (:)(:)
