The FM manual describes the parameters to be "the name of a compound variable". If you don't quote, REXX will try to dereference the variables, does not find them, and raises NOVALUE if activated. If not, those which were initialized (unsorted_data & sorted_data) are replace by a blank. I think the examples in the doc should be updated to quote any and all of the parameters which denote a stem variable. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
