OK, well, this works for me, too, then:

x = indgen(101)
y = cgDemoData(1)
errors = randomu(-3L, 101)*4
cgPlot, x, y
oploterror, x, y, errors, errcolor=cgcolor('black')

PS_END spawns the "convert" command to check for its presence.
If it can't find it, I presume it is because the "convert" command
is not on the path of the shell running IDL. Macintosh computers
are a bit of a mystery to me, so if you have a suggestion for how
I can solve this problem, I'm all ears.

Someone suggested a configuration parameter that could locate
ImageMagick. Maybe I'll look into that a bit.

Humm. That might be a PSConfig limitation. I'll look into it
and get back to you.

Cheers,

David
