Firstly you must understand the manner that variables are expanded and how batch scripts are interpreted.

Batch scripts are read line-by-line. Any variables are replaced with their values and then the line is executed; variables are updated after each line is interpreted.

Is the same as WINDOWS CMD.EXE, try it in cmd.exe you will get the same result。

OK! Thanks! but:

set * set x=8 set x=2 && call set y=%x^% #x=2 y=2 OK!

Yes,because call will get new line to run.
