China DOS Union

Which Chinese DOS can be used in the Win2000 command prompt?

It seems CCDOS97, UCDOS, and others all work.

UCDOS won't work, CCDOS97 can, and Tianhui probably can too.

UCDOS should work, right? I've tried it many times myself.

Under the Win2000 command prompt itself, it can already display Chinese and also input Chinese. What do you need a Chinese character support system for?

In full-screen mode, then you need a Chinese character support system.

Is ccdos97 green software?

CCDOS97 doesn't need installation. Just extract it into the CCDOS directory and you can use it.

DOS software is basically all "green software,"
What is the definition of green software?
It doesn't add files to the system directory,
doesn't add information to the registry,
can be used without installation,
and doesn't need uninstalling; just delete it directly and the software is gone. (That's how I understand it, not sure if that's right, hehe...)
DOS doesn't have any so-called system directory, and it doesn't have a registry either.
Most DOS software doesn't need installation. Even if there is an installer, it's just there to make it easier for you to copy files... (Basically, the function of a DOS installer is about the same as a batch file for copying files, hehe... of course, sometimes there are also processes like extraction or decryption. But mainly it's still mostly about copying files!)
After deleting DOS software, generally there's nothing left behind...

Some DOS software needs to modify autoexec.bat, which counts as slightly less green, but usually it just adds the path of the files it needs at runtime into the path variable. Some may put a certain executable into autoexec.bat so it runs automatically at startup. That's not really a big problem either.

There is also some DOS software that, for compatibility with windows, developed some inf files so that it can also run correctly in windows, but in a pure DOS environment there is no need to install those inf files. For example, ccdos has inf files for running under win95. Like the situation one friend on the forum ran into, it was because he installed ccdos's windows driver, and then irresponsibly (from windows's point of view) moved the location of CCDOS (which isn't much different from deleting CCDOS, at least windows can't tell the difference; whether you move it or delete it, as long as it can't find CCDOS and the related files in the specified location, it tells you it can't find them), and as a result the machine wouldn't even boot? (Actually that shouldn't happen. DOS software shouldn't cause that kind of result. I think at most you'd get a message like "you are missing a certain file, press any key to continue", and then you could just press any key and continue...

Actually, the installer in windows is basically the same as the installer in DOS; it just does more things. I once analyzed the installation process of a piece of software, then made an installer for it under DOS (a batch file). And the result was that after installing it this way, the software could still run correctly... the effect was the same as using the windows installer. Hehe... (That software was the lovely "Caizhi Home Finance", haha.)


Anyway, most DOS software is "green software," hehe...

Anyway, the UCDOS98 version works.
