Escape sequences vary in length. The general format for an ANSI-compliant escape sequence is defined by ANSI X3.41 (equivalent to ECMA-35 or ISO/IEC 2022). [12]: 13.1 The escape sequences consist only of bytes in the range 0x20—0x7F (all the non-control ASCII characters), and can be parsed without looking ahead. The behavior when a control ...

Specifically, they used ASCII code 27 10 (escape), followed by a series of characters called a "control sequence" or "escape sequence". The mechanism was invented by Bob Bemer , the father of ASCII. For example, the sequence of code 27 10 , followed by the printable characters "[2;10H", would cause a Digital Equipment Corporation VT100 terminal ...
This was later developed into ANSI escape codes covered by the ANSI X3.64 standard. The escape character also starts each command sequence in the Hewlett-Packard Printer Command Language . An early reference to the term "escape character" is found in Bob Bemer 's IBM technical publications, who is credited with inventing this mechanism during ...
An interesting (mis)feature of ANSI.SYS is the ability to remap any key on the keyboard in order to perform shortcuts or macros for complex instructions. Using special escape sequences, the user can define any keystroke that has a character-code mapping to simulate an arbitrary sequence of such keystrokes. [6]
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
The \n escape sequence allows for shorter code by specifying the newline in the string literal, and for faster runtime by eliminating the text formatting operation. Also, the compiler can map the escape sequence to a character encoding system other than ASCII and thus make the code more portable.
Title of this article should be "ANSI escape sequences" (with disambiguation pointing to it for "ANSI escape code"). There is only one ANSI escape code; what is described by this page is a sequence of ANSI codes, not the single ANSI code point (0x1C) for the code usually referred to as "ESC".
