VMS Help PRINT, Qualifiers, /PARAMETERS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /PARAMETERS=(parameter[(=value[,...])] [,...])

    Specifies from 1 to 8 optional parameters that are unique to a
    particular print symbiont. Each parameter and its values are
    passed as a single text string directly to the print symbiont:
    logical names and DCL symbols are not translated by the PRINT
    command.

    Each parameter can take from 1 to 8 values for a total of 255
    characters. If you specify only one parameter or parameter value,
    you can omit the parentheses. Enclose parameter values containing
    lowercase letters or nonalphanumeric characters (such as spaces,
    parentheses, or commas) in quotation marks.

    You can specify the /PARAMETERS qualifier only once in each PRINT
    command. For example, in the command PRINT /PARAMETERS=(JJJ,KK)
    /PARAMETERS=(LL,MMM), the JJJ and KK are ignored because the
    second occurrence of the /PARAMETERS qualifier supersedes the
    first occurrence.

    For information on parameters available for printing to
    PostScript printers using DECprint Supervisor software (DCPS),
    refer to the DCL Help topic PRINT_Parameter.
