Hi David,

there seems to be a problem if I had an array and I want to contour say
array(0,*,*). If I plot this outside of the loop by specifying my ith
position explicityly, and then loop from 1,n-1 then I am ok! Wierd.

I've also had issues doing the following

plot a map projection
plot shaded contours
plot line contours
plot the map again (since it is erased - even with /noerase)

Finally, by using /advance and !p=, etc... I worked it out! Nothing
complicated is ever simple!

Cheers

Mick....
