The character '^' at the end of line, escape what?

[.]

Code: Select all

@echo off 
echo a^ 
b 
pause

The result is 'ab'.

I know there are two characters '<carriage return><line feed>' at the end of line.

My question is '^' escaped '<carriage return>' or both '<carriage return><line feed>'? and why displayed 'ab'? Thanks.
