On startup, the DECNET_REGISTER utility always attempts to execute
an initialization command file if one is present. This is most
useful for pre-setting the values to use for command parameter
defaults.
DECNET_REGISTER checks for an initialization file using a default
name of:
SYS$LOGIN:DECNET_REGISTER.INI
If this file is found, it is automatically executed as a command file
containing a series of DECNET_REGISTER commands. If a different file
name is to be used, specify the file name using the logical definition:
$ DEFINE DECNET_REGISTER_INIT initialization-file-name
If this logical definition exists, #(NETREG_NAME) uses the
specified file name, rather than the default file name.
