This is not directly related with Tom Grydeland's problem, but it is annoying:
when using Internet Explorer, simple cut and paste from Exelis Website examples to the Workbench is not possible: all the lines get glued together, likely due to missing new line character(s) in the Exelis page. Is there a workaround ?

I don't, as stated previously, but I must have some other function or routine on my path that shadows some function being called by MAP(). I tried exactly the same with an IDL started with a default IDL search path, and creation of MAP objects works then.
Is there a way to get a backtrace from this error message? I'm being returned to $MAIN$ so as far as I know, my stack is lost.

It does.
What's even more screwed up, a colleague running exactly the same routine file with exactly the same IDL version on exactly the same machine does not see this problem. My IDL karma must be exceptionally weak this week.

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

I can't run that code either on my Windows machine, but I get though the
line above and crash on this one:
im = IMAGE(img, GRID_UNITS='meters', $
MAP_PROJECTION='Mercator', $
SEMIMAJOR_AXIS=6378137d, SEMIMINOR_AXIS=6378137d, $
DIMENSIONS=[800, 800], $
LIMIT=[lonlat0[1], lonlat0[0], lonlat1[1], lonlat1[0]], $
IMAGE_LOCATION=[x0, y0], $
IMAGE_DIMENSIONS=[deltax, deltay])
Where the lonlat variables are undefined.
Nevertheless, I did use this example as the basis for the OpenStreetMap
plot example in the Coyote Gallery. The code there works. :-)

David

Hi Alain,
I'll check into this.
