how refactor duty takes lots arguments?

i wrote coupling com vigilant wholly excepted strings input, good oop use i wrapped twine adult duty easier build call.

i only wondering anyone cruise improved proceed following code.

   open duty opentable(byval tablepath string, discretionary byval openas twine = nothing, _
            discretionary byval bury boolean = false, discretionary byval asreadonly boolean = false, _
            discretionary byval interactive boolean = true, discretionary byval evidence twine = nothing, _
            discretionary byval noindex boolean = false, discretionary byval viewautomatic boolean = true) tableinfo

            string.isnullorempty(tablepath) then
                pitch new argumentnullexception("tablepath", "tablepath can't zero empty")
            finish if

            low builder = new stringbuilder("open list ")
            builder.appendformat("{0}{1}{2}", controlchars.quote, tablepath, controlchars.quote)

            (not string.isnullorempty(openas)) following builder.appendformat(" {0} ", openas)
            (hide) following builder.append(" bury ")
            (asreadonly) following builder.append(" readonly ")
            (interactive) following builder.append(" interactive ")
            (not string.isnullorempty(password)) following builder.appendformat(" evidence {0} ", password)
            (noindex) following builder.append(" noindex ")
            (viewautomatic) following builder.append(" perspective involuntary ")

            mycomapp.do(builder.tostring)

            low fileinfo = new io.fileinfo(tablepath)
            relapse new tableinfo(fileinfo.name.substring(0, instrrev(fileinfo.name, ".") - 1))
        finish function

the volume arguments duty take biggest worry. too bad nonetheless there functions i competence have destiny take lot some-more arguments, i'm especially looking improved ways build infinite justification functions.
