Use the TELL prefix to identify the executor node for a particular NCP
command.   TELL sets the executor for only one command and must prefix
the command for  which  it  is  intended.   This  command  allows  you
optionally  to  specify access control information in one of two ways:
as part of the node-spec or as distinct parameters.

TELL    node-spec       ACCOUNT account
                        PASSWORD password
                        USER user-id

All underscores found in parameters must be replaced with spaces
when parameters are used in NCP commands.

specifies a node name or address optionally followed by
access control information as specified for VAX/VMS. Use one
of the following formats:

        node-id
        node-id"user password account"

identifies the user's account for access control
verification at the designated executor node.

identifies the user's password for access control
verification at the designated executor node.

identifies the user's ID for access control verification at
the designated executor node.

     NCP>TELL 3.5 SET KNOWN LINES ALL

         This command sets the executor to node 3.5 where the SET  KNOWN
         LINES ALL command executes.

     NCP>TELL TRNTO"LOW JBL"  SHOW KNOWN LINES

         This command uses  access  control  information  to  set  the
         executor  to  node  TRNTO  where the SHOW KNOWN LINES command
         executes.

     NCP>TELL TRNTO USER SYSTEM PASSWORD MANAGER ZERO EXECUTOR

         This command uses an alternate access control format  to  set
         the  executor  to  node TRNTO where the ZERO EXECUTOR command
         executes.
