Delete character

In computing, the delete character (sometimes also called rubout) is the last character in the ASCII repertoire, with the code 127 (decimal).〔(definition of the rubout character 7F hex )〕 Not a graphic character, it is denoted as ^? in caret notation and has a graphic representation ␡ in Unicode (as all other ASCII control characters have graphic representations).
There is no common method to input this character on modern keyboards, although in some environments (especially, Unix-like systems) the key or combination of and in, for example, Notepad may generate this code.
== History ==

This code was originally used to mark deleted characters on punched tape, since any character could be changed to all ones by punching holes everywhere. If a character was punched erroneously, punching out all seven bits caused this position to be ignored (or deleted). In hexadecimal, this is 7F to rubout 7 bits, and FF to rubout 8 bits. For teleprinters like the Teletype Model 33, lines were commonly ended by the three characters CR, LF, and rubout, with the rubout allowing time for the print mechanism to physically move to the left margin. On VT100 compatible terminals, this is the character generated by the key labeled Delete, which transmits a delete character (octal 177) to the host system.〔(【引用サイトリンク】url=http://www.vt100.net/docs/tp83/chapter5.html )〕〔(【引用サイトリンク】url=http://www.vt100.net/docs/vt100-ug/table3-4.html )〕 On VT510 compatible terminals, this is the character generated by the key labeled (unicode:⌫), usually called backspace on modern machines, and does not correspond to the PC "Delete" key.〔(【引用サイトリンク】url=http://www.vt100.net/docs/vt510-rm/chapter8 )
