Thanks,

Ah, that was easy!

Now here's 'How come #2'
I know that I can replace a given field in one of the structures.
How come I can't replace Array element X with an identical structure (as
I would with a named structure?)

IDL> S1 = {a:0, b:.1, c:''}
IDL> S2 = {a:3, b:7., c:'x'}
IDL> A = Replicate(S1,3)
IDL> A(1).c = 'q' ;replace a field value without a
problem
IDL> A[1] = S2 ; can't replace a structure.
% Conflicting data structures: S2,A.
% Execution halted at: $MAIN$

Thanks,
Ben
