Gaga~ The things in textbooks are all static. The most important thing is to know how to use them flexibly...

There's no way, Microsoft doesn't have instructions on this aspect.

Suggest that the moderator and electronixtar start a new thread to discuss posts about batch processing bitwise operations. :)

Because there are very few schemes for using bitwise operations in batch processing, and these bitwise operations are mostly very wonderful in games. :)

So, if we start a new thread to discuss, there are several advantages:

) Increase the advanced essence content of the forum (rarely mentioned and applied in other forums)
) Facilitate future retrieval of this bitwise operation knowledge point
) Through everyone adding content together to discuss this bitwise operation, make it lively! Increase popularity! Increase advanced popularity (Oh~ that's called increasing fairy qi~ :)

I saw nothing~~ I said nothing, I knew nothing~~

(Sneakily drag out Notepad to write code, read the help document in ntcmds.chm -_-! )

Hehe~ Just like what brother namejm said, the help of cmd is like a天书...

namejm is snickering aside. Oh, I was originally writing VBS irregular form code, and now it's interrupted again. Ugh

Wengier, come here quickly, there are a group of people chatting in the forum. The moderator qwe1234567 is leading the chat, go and ban all their IPs～～～

set /a a=0x01

set /a b=0x02

set /a c=0x01

set /a d=a^&b

set /a e=a^&c

```
set /a a=0x01
set /a b=0x02
set /a c=0x01
set /a d=a^&b

Running results:

Wengier, come here quickly, there are a group of people chatting here. Moderator qwe1234567 leads the chat, and let's all...

Writing a batch script to calculate lottery numbers is still interesting. When you win 5 million with the batch script you wrote, I'll give you 100,000. Haha...

Give electronixtar an extra point～:)

　　Thanks to brother est for writing the post about bit operations.

　　But it didn't write about what aspects of applications these bit operations have, which fails to arouse everyone's interest in bit operations. Everyone only knows the results of a few bit operations, and they can analyze them themselves, but what aspects can these bit operations be used in? I think giving a practical application example of bit operations can illustrate the problem better.

　　Strongly suggest brother electronixtar.........heh, you know what I mean...... d= =b

Well then, I put forward a direction for everyone to study. Using batch processing to do base64 encoding, and it will make bit operations very enjoyable.

Great, this is exactly what we need.

Such a fun idea, you should start a new thread~ : )
Leave the very attractive content outside (the title should have it), so that more people will see it as soon as they enter the forum, which is also promotion and popularity~ : )

It's really difficult to use DOS batch processing to do BASE64 encoding without using external tools to read binary and then encode it : (
I estimate that VBS is suitable?

js is appropriate. js also supports bitwise operations
