Can be used to add headers/titles too. stocklist assign each quote each stocklist NB. only have to edit stocklist once, and you will get new variable names.

UALp and DALp are assigned plot each ". each stocklist ,each 'p' NB. would repeat above 2 plots, and simpler below (but this line works for any number of items in stocklist) plot each UALp ; DALp The wow punchline is that only stocklist need be changed to get specific whole new variables, and stocklist can be very long. ----- Original Message ----- From: Joe Bogner <joebog...@gmail.com> To: programm...@jsoftware.com Cc: Sent: Monday, February 17, 2014 3:25:39 PM Subject: Re: [Jprogramming] J in 5 minutes On Mon, Feb 17, 2014 at 3:21 PM, Pascal Jasmin <godspiral2...@yahoo.ca>wrote: > If you post your script file, I'd be happy to suggest lines for the > console. > > Hi Pascal, I posted it to chat: http://jsoftware.com/pipermail/chat/2014-February/005702.html ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
