## Arrays

NetRexx also supports fixed-size arrays. These are an ordered set of items, indexed by integers. To use an array, you first have to construct it; an individual item may then be selected by an index whose value must be in the range `0` through `n-1`, where `n` is the number of items in the array:

      array=String[3]        -- make an array of three Strings
      array[0]='String one'  -- set each array item
      array[1]='Another string'
      array[2]='foobar'
      loop i=0 to 2          -- display the items
        say array[i]
        end

This example also shows NetRexx line comments; the sequence '`--`' (outside of literal strings or '`/*`' comments) indicates that the remainder of the line is not part of the program and is commentary.
