China DOS Union

I want to use BAT to do file association, but there is a small problem, ask experts to help solve!

For example, I want to associate the .jsb file to be opened with Notepad. The following is the command, which can be realized under the DOS command prompt
Assoc .jsb=jsb
Ftype jsb=C:\WINDOWS\system32\notepad.exe %1

But I want to use BAT to realize batch processing to associate files. The following is the BAT script
@ECHO off
cls
color B
ECHO.
ECHO JSB file association
ECHO.
pause

Assoc .JSB=JSB
Ftype JSB=C:\WINDOWS\system32\notepad.exe %1

ECHO.
ECHO JSB file association succeeded
ECHO.
pause
exit

Problem, I use the same command, which can be realized under the command prompt, but cannot be realized in BAT. Why? Under the command prompt, I can define the variable of 1%, but in BAT, I cannot realize the variable of 1%, and after opening, it is empty! Please tell me how to solve it by experts. How should I write BAT? I think I have a wrong writing format.

Thank you. I wrote the BAT like this:

@ECHO off
cls
color B
ECHO.
ECHO JSB file association
ECHO.
pause


Assoc .JSB=JSB
Ftype JSB=C:\WINDOWS\system32\notepad.exe ^%1

ECHO.
ECHO JSB file association succeeded
ECHO.
pause
exit

But still can't control the 1% variable. In the command prompt, I can define C:\WINDOWS\system32\notepad.exe %1. In the BAT, it's just C:\WINDOWS\system32\notepad.exe without 1%, so it can't read!

Please help me again, thank you!

That 1% is for controlling the open function. If there is no 1%, it just opens an empty Notepad. With 1%, it can load the content in the file.

In the command prompt, you can add the %1 variable, but in BAT, you can't add the %1 variable.

In BAT, the definition of C:\WINDOWS\system32\notepad.exe %1 is that the %1 after C:\WINDOWS\system32\notepad.exe cannot be loaded.

OK, thank you. Just two % signs are enough!!!

Haha, thank you! I'm a novice, learned something new!

There is another question. I want to ask, the Windows or WIN of the system disk can be defined with %SystemRoot%. Then what is used to define the system's Program Files! Thanks.

Okay, found it. Thanks!

Just run set yourself and see.

The answer is:

%ProgramFiles%
