 LOGIN userid

 LOGIN allows you access to the system if you have a valid acount.

 'userid' is either your last name, or a UIC with the two numbers separated 
 by either a comma (,) or a slash (/). The square brackets ([]) are optional 
 for this command. After entering your userid, you will be prompted 
 for your password.  The password will not echo on the your
 terminal. You can enter the password on the same line as the LOGIN
 command by preceding it with a slash, but your password will be 
 echoed.

 If the userid and password are valid, you will be logged on the system.
 The login message file, LB:[1,2]LOGIN.TXT, will be printed on your
 terminal, unless you entered 'userid' as a UIC separated by a slash, in
 which case only the most recent messages will be printed. If you have
 a login command file (LOGIN.CMD) in your directory, it will then be
 executed.

 LOGIN and HELLO are identical, but LOGIN does not work on systems 
 without DCL.
