escape $ in expect script

#!/bin/bash
/usr/bin/expect << SSHLOGIN

spawn ssh -o StrictHostKeyChecking=no admin@$host

expect {
    Password: {
        send "Pass$word\n"
        expect {
            OK: {
                send "xstatus\n"
                send "quit\n"
            }
        }
    }
}
SSHLOGIN

It is not able to ssh because it is not escaping the '$' character in "Pass$word\n" since $ is part of the password and there is no variable being passed. How would you escape it? I know in bash, you would add '\', but since the password is in the expect script portion, that does not work.

EDIT: changing Pass$word\n to Pass\\\$word\n works

Here-documents are bash code, so you'd still use \$.

The expect script is TCL, so you'll need to escape the $ there too. With two levels of escaping, you get:

send "Pass\\\$word\n"
