Isn’t it because it is simply the control code + 0100 to arrive at the
capitals column of the ascii table? (http://www.asciitable.com)
Hence ^@ for NULL and ^[ for ESC.
Amusingly in the UNIVAC FIELDDATA character set.
The @ had the value zero
(and was called the master space).
That wouldn't have anything to do with how ^@ is a somewhat common
representation of 000, would it? (Yes, using octal on purpose.) I've
always kind of wondered where that notation came from.
That ^A through ^Z were representations of 001 through 032 makes more
sense.
