Thanks to Roger for this clarification. I took the splitting of the variables to be a consequence of the delimiter and not just a benign consequence of the printed output (at least I presume this is the proper interpretation of Jan's problem.) The tab character is of course included in "whitespace"....using "\t" explicitly would be helpful if there is embedded whitespace (other than a tab) within a field.
