Library /sys$common/syshlp/ncphelp.hlb TELL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 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

 You cannot use the TELL prefix with the CLEAR EXECUTOR NODE, COPY
 KNOWN NODES, or SET EXECUTOR NODE commands.

  Additional Information (explode) :

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