Thanks for the info.

New plotting functions support only inline plots.
I think the basic plotting functions should use only one output terminal for 
gnuplot.
If you want to get both inline plots and external plots at the same time, 
you should program a new function in Maxima.
But this is the open-source project, so you can do what you want :)

You can get an arbitrary return value.
If you want to get the return value "true", you should add (return-from nil t) 
as follows:
