Either you hardcode them in the program, or you read Getopt::Long, which will explain to you how an option is handled if it is given multiple times. Also, as I now see, there is documentation at the bottom of the file which shows exactly your use case of specifying multiple columns. Maybe you should read that documentation first?	[reply]
