echo in alias for Unix C-Shell Prompt

Hi,
I want to set Unix prompt in C-Shell which required the break new line using alias.
Ex.
hostname : username : [$CWD]
%>

Now, it will be setup in .login file with alias
alias cd 'cd \!* | set prompt="`hostname` : $USER : [$CWD] %>"'

I'm unable to parse echo command or break which I can get %> in next line.

Thanks
