Thank you for your replies. I had studied the IDL_KWProcessByOffset documentation and could not immediately retrieve the number of keyword using the function. I now simply add the nkw=sum(kw.there) flag, which are set to one if the keyword is set. Then I compute argc-nkw to get at the number of regular arguments.
