In the English 26 letters,
In FOR, they are all variables, and there is no difference.

What does the following "echo %+/%,/%-" mean?

There are definitely more than 26 symbols:

for /f "tokens=1,3,4" %+ in ("hello world batch fans") do @echo %+/%,/%-

What does the following "echo %+/%,/%-" mean?

Can you explain the meaning of the code on the seventh floor? I don't understand it, thank you! :(

Code on the seventh floor
for /f "tokens=1,3,4" %+ in ("hello world batch fans") do @echo %+/%,/%-

Read "hello world batch fans", split into individual tokens according to the space (default) delimiter, take the 1st, 3rd, and 4th tokens, and assign them to %+ %, %- respectively (because according to ASCII code values, 43 corresponds to +, 44 corresponds to ,, 45 corresponds to -). So %+ is hello %, is batch %- is fans

The final result is hello/batch/fans

Learned, it seems that it should be done in ascending order of ASCII. As for the statement that there are only 26 letters, I have also seen it, maybe it's a problem with different Windows versions.
