Thanks for that clarification. This leads to my next question! :-) Are the world coordinates given to plenv etc the projected (i.e. transformed) world coordinates? If one has setup a transformation like the example you included in you original message, would a "plline" call to plot a line between points of equal latitude but different longitudes still draw a straight line while a "plpath" call to do the same would draw an arc according to the established transformation? Maybe this will all be obvious once I actually read the docs and look at the example code!
