中国DOS联盟

May I ask, in a pure DOS environment, how to open a folder with a Chinese file name? (Preferably without relying on software or creating batch files)

In pure DOS, Chinese characters cannot be displayed (they appear as garbled code). I once asked my teacher how to enter the "D:\Operating System" directory in pure DOS, and he actually calculated the four characters "Operating System" with a pen! The result was eight groups of three-digit numbers (178, 217, 215, 247, 207, 181, 205, 179). Each two groups of numbers were one character. In pure DOS, the garbled form of the four characters "Operating System" was typed out (the method was to hold down the "Alt" key, then press the number keys on the numeric keypad, then release the "Alt" key. One time was half a character, and it was typed eight times to finish these four characters!)

I want to ask who knows how these eight groups of numbers were calculated.

Really, I don't know what encoding is used. It's best to have a simple algorithm. It's really great.

Unfortunately, the displayed text is still garbled. It can only be displayed under the Chinese system

Re king603:

In general, Chinese systems under DOS use the GB2312 character set national standard encoding. There are very few Chinese character systems that use larger character sets such as GBK or CJK. In GB code, Chinese characters are divided into first-level Chinese characters and second-level Chinese characters. The first-level ones are arranged in pinyin order, and the second-level ones are arranged according to strokes and the number of strokes. Although there is a certain pattern, strong memory of the encoding table is necessary for actual calculation, and it is generally not recommended.

And there have been many solutions for entering Chinese-named directories (or opening folders with Chinese file names) without using a Chinese system under DOS. Here is a link for you:

Of course, the existing solutions still cannot be completely achieved. For example, in a random environment containing many Chinese-named directories of the same length, but not telling which Chinese names they are, and only requiring entering a directory named "Target Directory", it is very difficult to achieve.

You can obtain the character values of those "garbled codes" by querying the ASCII character table. Both DN (DOS Navigator) and the help files of QB/QBasic have ASCII tables. As for how to calculate the ASCII code values of each Chinese character, you can compile a small program to convert ASCII characters to numerical values.

If you don't rely on any tools, then you can only rely on memorizing the ASCII code values of those characters by rote -_-

Can everyone give an example of conversion?

For example, how is the character "系" converted?

Yeah, it would be best to give a few examples so that we all can learn from them!

Take QB as an example:
a$ = "系"
PRINT ASC(LEFT$(a$, 1)); ASC(RIGHT$(a$, 1))

As shown in the figure:



Is there a formula that can be used to calculate these eight groups of decimal numbers?

Each character corresponds to an ASCII code, so the formula is to convert the ASCII character to the code.

How to convert to code? What are the steps?
Please teach...
Thanks!

It seems a bit related! But still not very understanding~~~~~~ (I'm too stupid~~?)

For example: In "操" = "178 217", if the result answer is "178 217", then, is there any other information as "known conditions" besides the character "操"? What are those so-called implicit "known conditions"? (I seem to have asked too abstrusely~~~) Or, is this result answer of "178 217" only computable by a computer and simply impossible to be calculated manually?

Please look at the above area code table. The country has assigned a location code to each Chinese character: there are 2 numbers, the first is the area and the second is the position (nonsense?). If you want to calculate the desired number, first find a character in the table, for example, "藏" is in area 18, position 56, then add 160 respectively to get 178 and 216, which is actually the internal code of the Chinese character.
