How about this...

pro test
a=['I','E','F','D','A','J','C','B','G','H']
b=['E','B','I','J','D','A','C','H','F','G']

qa=sort(a)
qb=sort(b)
qa2=sort(qa)
elements=qb[qa2]

print,b[elements]
end

IDL> test
I E F D A J C B G H

Sorting the sorted indices is the trick. I think it's right, but it
makes my head hurt anyway.

regards,
Greg
