China DOS Union

Nowadays, most of the ASCII code tables found online lack special control symbols, so I made one myself and give it to everyone. In DOS, all ASCII characters can be entered using ALT + the number keys on the numeric keypad. For example, ALT + 10 enters the line feed character, ALT + 13 enters the carriage return...

I usually look up ASCII codes from QB's help files or DOS Navigator. This table is very beautiful, moderator! It's very much like the table in a DOS textbook. I'll give it a thumbs up.
I wonder where those control characters come from? Did the moderator draw them himself?

There are several symbols drawn by myself, and most characters are available in Windows fonts.

Re Lydong:

Nice topic, hope to continue to enrich the content in it.

In fact, there are many resources and information to refer to about the origin, divergence and arrangement rules of the ASCII code table. Here are two suggestions:

1. Separate the ASCII code table from the extended ASCII code table, because they are not formulated by the same organization ANSI (the former is ANSI, widely adopted in the world, with minor differences; the latter is IBM, quite popular on its PC product line, but there are also other organizations formulating different code tables), and the applicable occasions are also very different, and it is also conducive to the display and browsing of pictures.

2. There is a column code mapping in the code table that is not mentioned, that is, the mapping between column 0/1 and column 4/5. From 00h to 1Fh, they can be respectively corresponding to Ctrl+@(^@), Ctrl+A(^A), Ctrl+B(^B), ..., Ctrl+Z(^Z), Ctrl+[(^\), Ctrl+\(^\),... That is to say, the control character Nul can be input through Ctrl+@, the screen displays as ^@, and the escape function is still an empty character.

According to the suggestion put forward by willsort, the ASCII code table has been newly modified in [the first floor].

Re zrh4019:

The basic ASCII and extended ASCII code tables from MSDN have been seen before, which are relatively close to DOS. It is recommended that everyone also take a look and compare the similarities and differences with the code tables in this version.

Another relatively useful code table resource around is the "Character Map" in "Accessories". After selecting "Advanced View", then select the character set related to DOS, and then change the font, you will find that there are quite large differences in the support of code tables by different fonts.

You can refer to MSDN

Referenced the "ASCII Character Code Chart" in MSDN, made a little modification to the above table, see .

Learned to, review and revise.....

Accumulate, and then accumulate; study, and then study

Good stuff, already collected. Thanks to the LZ

Good, very good, downloaded and studied.

I'm a newbie, what's the use of this thing?

For example, in the previous DOS era. The character interface for writing software...
