1    /AUTHENTICATE

    Specifies that Kerberos authentication should be used for
    acquiring access to the remote node.

2    /TERMINAL_TYPE

       /TERMINAL_TYPE=type

    Sets the terminal emulator to one of the following terminal
    types: VT100, VT200, VT300, VT400, VT500.

3    /TRUNCATE_USERNAME

    Specifies that the current user name should be truncated to 8
    characters before attempting to connect to the remote node. The
    qualifier is required for communication with systems that limit
    the size of their login names to 8 characters. The /TRUNCATE_
    USERNAME qualifier is ignored if /USERNAME is specified.

4    /USERNAME

       /USERNAME=username

    Specifies the user name for logging in to the remote node. The
    user name can be enclosed in quotes to preserve the case of the
    user name for case sensitive systems such as UNIX systems. If the
    /USERNAME qualifier is not specified, the default is the current
    user's user name.
