Greetings,
There must be a real simple way of doing the following but my
knowledge of IDL is real limited.

I have three 1-D arrays. Each array contains numbers from 1 to 1000.
But they differ because the arrays contain different arrangements of
numbers and different number of number.

I would like to get a list of numbers that exist in all three arrays.
In terms of groups I have three groups and I want to know what the
intersect is.

Any suggestions?
Thanks in advance,
Plim
