Don;

Once a NAMED structure has been defined, it cannot be redeclared differently.
Thus, you would have to create an anonymous structure. If you are trying to
do this in an object, that won't work. The values of the data can change from
one instance of the structure to another, but the names and types of variables
in the structure can't. At the IDL command line, try the following:

struct = {data:0}
struct = {mydata:0}

This will neither cause errors nor get ignored, but your structure will be anonymous.
