Hi. A few things about ⎕plot:
1) GNU APL info manual says (2.31): ⎕PLOT ¯3 ⍝ close all plot windows However: ⎕plot 2 1 4 3 94820426042176 ⎕plot ¯3 *** Could not find w_props 0xfffffffffffffffd in plot_stop() *** 0 [After that, further ⎕plot calls randomly display older plot data, if any.] 2) Is there any way to reuse on the same plot window (instead of storing/closing the handle and creating a new plot window every time)? (Likewise the default "plot()" behaviour of GNU Octave.) 3) Info manual (2.31.3) says that a plot can be closed "by opening the drop down menu of the window (at the top left of the window)", but that seems to be system-specific. Here, I can find a similar menu but right-clicking the window-manager border at the top of the window. Hudson
