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.
