I can not use sql command line (1 reply)

I just installed MySQL on Vista. Tomcat servise started, MySql service started,

I got to MySQL 5.5 command line client and logged as root
so I am at mysql prompt.
But now no matter what command I type I am getting msg
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'mysql
admin' at line 1

I am trying now to create database. I believe that I need first switch to mysqladmin by mysqladmin -u ; and then type create dbname;

Can you help - what I am missing?
Thanks.
