The USE SYSTEM command specifies the Gateway node that will be used
for subsequent SNANCP commands.

If you do not issue a USE SYSTEM command, then SNANCP will use the
translation (if any) of the logical name SNAGM$GATEWAY as the default
Gateway node.

FORMAT:

       USE SYSTEM node-name [access-information]

Additional information available:

node-nameaccess-informationaccess-definitionExample

This is the name of the Gateway node that will be queried for
information by subsequent SNANCP commands.

When you enter access control information with the USE SYSTEM command,
there are two possible formats:

        USE SYSTEM node-name USER username PASSWORD password

or      USE SYSTEM node-name"username password"::

You can specify either privileged or nonprivileged access control
information.  Usually, privileged access control information is
required if you wish to modify the running Gateway configuration.
Nonprivileged access control may or may not be required to display
information, at the choice of the Gateway manager.

The privileged user name and password can be defined in the
configuration command procedure during a Gateway installation.  To
change the user name and password, either edit the configuration file
and reboot the Gateway, or use NCP interactively.

Similarly, the nonprivileged user name and password can be added to
the Gateway configuration file, or use NCP interactively.

The NCP commands to establish or change this information are:

        NCP> SET EXECUTOR NODE gateway [USER olduser PASSWORD oldpass]
        NCP> SET EXECUTOR PRIV USERNAME username PASSWORD password
        NCP> SET EXECUTOR NONPRIV USERNAME username PASSWORD password

     1.  SNANCP> USE SYSTEM POPART USER WARHOL PASSWORD ANDY

         This command specifies the Gateway node POPART as the
         executor node for subsequent SNANCP commands.  The privileged
         username WARHOL and privileged password ANDY will allow you
         to use all SNANCP commands and to see all information in
         displays.  If you don't enter the privileged access
         information, you can enter only EXIT, HELP, SHOW, and SPAWN
         commands.

     2.  SNANCP> USE SYSTEM F111 USER ROSENQUIST PASSWORD JIM

         This command specifies the Gateway node F111 as the executor
         node for SNANCP commands.  The nonprivileged user name
         ROSENQUIST and nonprivileged password JIM allow you to use
         the EXIT, HELP, SHOW and SPAWN commands.  Some fields of the
         SHOW displays will merely indicate *SET* for nonprivileged
         users.

         If a nonprivileged user name and password are defined, you
         cannot use any of the SNANCP commands unless you specify the
         nonprivileged information.
