Of course, DIPSO generally does nothing that you don't ask it to do. So, if `nothing' happens, it is probably because you've defined X and Y ranges that exclude the data, or left the BOX switched off (NB), or you're not plotting on the device that you think you are. Something else to watch out for is plotting a STACK entry, and then trying to do some operation on the plotted data instead of the data in the `current' arrays. Be careful!
DIPSO carries no `memory' of what's on a particular plotting surface.
This means that if you want a laser-printer plot of what's on the
screen you need to change device and actually do the plot again (don't
forget to change back to your graphics terminal when the plot is
