The DECNET_MIGRATE utility is normally invoked using the RUN command.  It
 may also be invoked using a foreign command symbol.  For example:

     $ RUN SYS$UPDATE:DECNET_MIGRATE                 !Invoke the utility

     $ DECNET_MIGRATE :== $SYS$UPDATE:DECNET_MIGRATE !Foreign command symbol
     $ DECNET_MIGRATE                                !Invoke the utility

 If a foreign command symbol is used, a command line may be passed directly
 to DECNET_MIGRATE on the invocation command line.  For example:

     $ DECNET_MIGRATE EDIT NCL_COMMANDS.COM

 The EXIT command will cause DECNET_MIGRATE to terminate execution.  The
 <Ctrl/Z> key combination may also be used.

 If a command was specified on the invocation command line, the utility
 will exit immediately after the command has been processed.
