This paper is intended to propose character constants for C to align with this proposal, since such characters have been shown to be useful in existing practice within shells, and are somewhat more complex to do in a portable fashion by existing mechanisms.
In the basic execution character set, there shall be control characters representing alert, backspace, carriage return, and new line.to
In the basic execution character set, there shall be control characters representing alert, backspace, carriage return, new line and escape.Add the following to 5.2.2 paragraph 2 in the correct alphabetic order:
Add the following new subsection, numbered 126.96.36.199 before 5.2.3:
\cx The character representing "CONTROL-x", where x is a single alphabetic character, as described in section 188.8.131.52. \e The escape character
184.108.40.206 Control Characters
The following table describes a mapping between CONTROL characters, as introduced by \cx, and characters in the current character set. NOTE - Many of these characters are not required to be a part of the basic execution character set. If the current character set does not include any equivalent character for any of these, an implentation defined alternative character may be used.
