Yeah, the problem is solved now.
 I changed the path after
 SET TMP=%RAMDRIVE%\TEMP
 SET TEMP=%RAMDRIVE%\TEMP
 PATH=%RAMDRIVE%.;%RAMDRIVE%\SYSTEM
 and now no matter where I am I can run the stuff in those two folders.

 But why exactly?
 I still don't understand!!

That's because DOS automatically searches for programs in all the paths specified in PATH.

But I changed the path statement in
:NEXT
SET SM=
SET DIRCMD=/OGN /4
SET PROMPT=$P$G
PATH=%PATH%;C:.;A:.;..
like this:
:NEXT
SET SM=
SET DIRCMD=/OGN /4
SET PROMPT=$P$G
PATH=%PATH%;C:.;A:.;C:\masm6;c:\bc31\bin;..
but it still doesn't work. Why is that?

Master Rushi:
I still don't really understand that % question I mentioned above, let me give an example.

1.SET TMP=%RAMDRIVE%\TEMP
2.SET TEMP=%RAMDRIVE%\TEMP
3.XX1=%XXXX1%
4.XX2=%XXXX2%
5.PATH=%RAMDRIVE%.;%RAMDRIVE%\SYSTEM

Do 1 and 2 above represent %1 among the variables? And do 3 and 4 represent %2 and %3 respectively? Is that the right way to understand it?

Then in 5, what do those two pairs of % represent? Are they %4 and %5 among the variables?

In a .bat, can you not use more than 9 pairs of %?

I'm very much a newbie, hope no one laughs at me.

Why is it that after running MSCONFIG under WIN98 and viewing the AUTOEXEC.BAT file, the batch processing on every machine is different? What exactly do they do?

Usually the autoexec file in win98 is empty...
It's information written in when some software gets installed... not very useful...

My machine keeps hanging. Can I check it from DOS?

Explain in detail...

Master Rushi:
Please help answer my question, this problem has bothered me for a long time.

That understanding is wrong. %RAMDRIVE% is the RAM drive space. Since the drive letter of the virtual RAM drive is not fixed, % signs are used here to specify it. 3 and 4 are what specify variable values... so DOS can call them.
Generally speaking, the ten variables %0 to %9 are replacement variables...
while %RAMDRIVE%, %cdrom%, etc. are environment variables specified by the set command....

Then is it like this:
A=%a1% (this is %0)
B=%b1% (this is %1)
C=%c1% (this is %2)
D=%d1% (this is %3)
……
……
But then you can't have more than 9 settings, meaning it can't go beyond %9.
For example, if under DOS I enter DIR A, it automatically calls a1.
Is that right??

Mm... yes...

Everyone:
I urgently need a large number of bat files, like tutorials, examples

I still don't understand batch processing very well. I hope all you experts can kindly teach me.

Yeah, an expert is an expert, I admire you.

When I was in college I had an idea: to use autoexec.bat to write a virus (of course not a destructive one, I just wanted to prove it was feasible), but I never actually did it. Now I've forgotten all my computer knowledge, so it's even less possible. If any expert is interested, you can give it a try. Remember to hint that it was written by a Chinese person.
