plot is a cover for pd, and is intended to take options as left argument and data as right argument, converting them into pd calls. Quite unintentionally, if you gave data in both left and right arguments, plot in J504b just gave both arguments to pd. This explains why plot/a,:b worked (since this is just a plot b). This stopped working in J6, because a utility used in plot was not converted properly for the change in explicit arguments (from y. to y). This is fixed now, so plot/a,:b works again. A slightly better way to show two lines is to have y as a two row matrix, e.g. x=. i.10 y=. 0 5 +/ *:x plot x;y ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
