All entries in the ASCII table below code 32 10 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text. The code 127 10 is also a control character. [1] [2] Extended ASCII sets defined by ISO 8859 added the codes 128 10 through 159 10 as control characters. This was primarily done so that if ...
Code 7F hex corresponds to the non-printable "delete" (DEL) control character and is listed in the control character table. Earlier versions of ASCII used the up arrow instead of the caret (5E hex ) and the left arrow instead of the underscore (5F hex ).
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received.
English: US-ASCII (1967) Code Chart. "SUB" (column 1 / row 10) and other symbols were introduced with the 1967 revision. Control Characters: (see File:US ASCII Control Character Symbols.png )
The block contains all the letters and control codes of the ASCII encoding. It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character.
In the control codes area (the C0 range), the Spectrum mostly uses proprietary controls, such as INK and PAPER to control foreground and background colour. However, the common BS and CR code points are the same as in ASCII. Cursor-down (0x0A, ASCII Line Feed) can be simulated with 32 spaces printed with OVER 1 (transparent overprint) and cursor ...
This code would be converted to 000 0001, corresponding to the ASCII character with id 1 (the SOH Character). The table at C0 and C1 control codes § C0 controls shows the ASCII control characters, with the "Caret notation" column showing a caret (^), followed by the character to press while the Control key is held down to generate the character.
