I'm trying to concatenate two structures using:
plot_params=[TEMPORARY(plot_params), tmp_struct]
but get:
% Conflicting data structures: TMP_STRUCT,concatenation.
But the structures have exactly the same tag names, and the type of data,
INT, FLOAT, etc, is the same for each tag in both structures. I even put
a STOP statement before the concatenation to double check the structures.
Am I missing something?
cheers,
S

I'm back in the office and getting caught up.
Pavel has already pointed out the solution to this.
I just want to let you know, however, that this
kind of thing *will* be possible in IDL 5.4. :-)
Structures that set aside the same amount of storage
space will be allowed to be concatenated like this,
despite having different "internal" names.
Cheers,
David
