       /CONFIGURATION=(keyword[,...])

    Specifies how the configuration choices will be supplied.
    Keywords are:

    CURRENT        This is the default. It uses values from the
                   product database, which has the current values
                   recorded from the last time the product was
                   installed or reconfigured.

    PRODUCER       Uses values specified by the software manufacturer
                   for this version of the product.

    INPUT=pcf-     Uses values from the specified product
    name           configuration file.

    OUTPUT=pcf-    Writes configuration choices to the specified
    name           product configuration file. If no file
                   name is supplied, creates a file named
                   DEFAULT.PCSI$CONFIGURATION.

    The keywords CURRENT, PRODUCER, and INPUT are mutually exclusive.
    Each of these, however, can be used with the keyword OUTPUT. If
    you specify only one keyword, you can omit the parentheses.
