Kinda roundabout, isn't it? Why not write directly to the path specified? Not indicative of a high degree of craftsmanship. ...Finally, using the TSO command, OEDIT allows the user to view it. Copying the path name does use a Carriage Return/Linefeed (CR/LF) to separate the file records. <CR><LF>!? Ugh! Not the z/OS Unix System Services convention. I see no mention of "tail" in Chapter 6, much less of "tail -f" (presuming that such dynamic updating was among the OP's objectives). I doubt that "tail -f" would be effective. > >> -----Original Message----- >> From: Paul Gilmartin >> Sent: Friday, 14 November 2014 1:56 AM >> >> On Thu, 13 Nov 2014 08:39:13 -0600, Elardus Engelbrecht wrote: >> >> >To Lizette: The word 'tail' is an Unix term where you send the last x lines >> >to >> somewhere else.
