Thanks for the new information. However, I'm not able to reproduce the problem.
What happens when you copy/paste the following commands to the IDL> command prompt to run?
common mycommon, a, b
a = {mystruct, $
aa : 1.23, $
bb : 1.23, $
cc : 1.23, $
dd : 1.23, $
ee : 1.23, $
ff : 1.23, $
gg : 1.23, $
hh : 1, $
ii : 1, $
jj : 1, $
kk : 1, $
ll : 1 $
}
b = replicate(a, 5000, 5000)
help, a, b
print, b[1000,1000].aa
And then enter this statement at the IDL> command prompt:
b[1000,1000].aa
If this doesn't reproduce the problem, can you provide stand-alone IDL commands with hard-coded data, and steps to follow, that I can use to try to recreate the problem on my machine?
