Editing Escape sequence (section)

==ASCII video data terminals==
The [[VT52]] terminal used simple [[Digraph (computing)|digraph]] commands like escape-A: in isolation, "A" simply meant the letter "A", but as part of the escape sequence "escape-A", it had a different meaning. The VT52 also supported parameters: it was not a straightforward control language encoded as substitution.

The later [[VT100]] terminal implemented the more sophisticated [[ANSI escape sequences]] standard (now ECMA-48) for functions such as controlling cursor movement, character set, and display enhancements. The Hewlett Packard [[HP 2640]] series had perhaps the most elaborate escape sequences for block and character modes, programming keys and their soft labels, graphics vectors, and even saving data to tape or disk files.

===Use in DOS and Windows===
A utility, [[ANSI.SYS]],<ref>{{cite book

The rise of [[GUI]] applications, which directly write to display cards, has greatly reduced the usage of escape sequences on Microsoft platforms, but they can still be used to create interactive random-access character-based screen interfaces with the character-based library routines such as [[printf]] without resorting to a GUI program.

===Use in Linux and Unix displays===
The default text terminal, and text windows (such as using [[xterm]]) respond to ANSI escape sequences.
