Hi David,

Thanks for the response. I think there is more to this problem than is
apparent at first. I believe that my structures are created identically.
It is the output of a complicated procedure. The structure is defined
inside the procedure and they should be the same each time. And just to
check this, I ran your example from above and here is the result:

IDL> a = { data:FltArr(10), name:'First Structure' }
IDL> b = { data:FltArr(10), name:'Second Structure' }
IDL> c = [a, b]
% Conflicting data structures: B,concatenation.
% Execution halted at: $MAIN$

Rather curious. I wonder if this is a MacOS version problem!

Cheers,

- Saeid
