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.

1  –  node-spec

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

         node-id
         node-id"user password account"

2  –  ACCOUNT account

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

3  –  PASSWORD password

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

4  –  USER user-id

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

5  –  Examples

      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.
