Hi Tom & David,

I think that the example is somewhat messed up. I'll have the docs team take a look. However, Tom, you should be able to run that MAP() line without any problems. Is it possible that you have another map function somewhere on your IDL path? Try the following:

m = map()
print, routine_filepath('map',/IS_FUNCTION)

It should point to the map.pro in the lib/graphics directory.

Hope this helps.

Cheers,
Chris
