Hey!
I have a struct something like this:
struct {
        const char * attribute;
        int size;
        int datatype;
}
...and I am trying something like this to match an NBExternalStructure:
fieldsDesc
        ^#(
                String attribute;
                int size;
                int datatype;
        )
...or even this:
^#(
                NBExternalString attribute;
                int size;
                int datatype;
        )
All these give me some DNU (nil) for #asAJOperand when emitting code.
The only one that works is when I use NBExternalAddress as can be seen in
action in NBTestStructure2. Is this by design or am I simply an early
adopter and support for String etc isn't there yet?
I think it is not  working because NBExternalString is quite special
when it about handling the
values.
For structure, i think, you'd better use 'char *' , or 'void*'..
and then to read string you can do:

struct attribute readString
