BCP Beginner - Please Help

Hi,

I am completely new to the BCP utility and fairly new to SQL Server

I am learning from a book and I am trying the following example (the server
I'm learning on is called contractor and a password has not been give to the
sa)

bcp pubs..authors out authors.txt -C -r
-t, -U sa -P -S contractor

When I run this in Query Analyser i get the error message..

Server: Msg 170, Level 15, State 1, Line 1
Line 1: Incorrect syntax near '.'.

I have tried puuting quotes around the database and the table name as
follows-

bcp "pubs..authors" out authors.txt -C -r
-t, -U sa -P -S contractor

and get the error

Server: Msg 179, Level 15, State 1, Line 1
Cannot use the OUTPUT option when passing a constant to a stored procedure.

Please can anybody help me to get this first bit working?

Thanks in anticipation.
