Structure fields can be indexed similarly to arrays. Use syntax similar
to:

for i=0, n_elements(tag_names(My_struct))-1 do help, My_struct.(i), /struct

This will step through all sub-structures in My_struct. Notice that you
MUST use parenthesis, not [ ] brackets, when indexing structures.
Cheers,
Pavel
