I recommend to work whenever possible with templates.
Example with your data:
dcl-ds xmldata;
file_in like t_file-in dim(100);
cnt_file-in int(5);
end-ds;
dcl-ds t_file_in template;
dcl-ds header;
dcl-subf file_number int(5);
end-ds;
service like tsf_service;
end-ds;
...

I think you meant to use LIKEDS, not LIKE.

With LIKE, file_in would be a CHAR subfield, not a sub-data-structure.

But aside from that, it's interesting that you prefer templates. One of the reasons we added nested data structures to RPG was because it could be difficult to understand complicated data structures for XML-INTO when the final data structure definition was spread out over several small data structures.

So, for me, the only time I would use a template for one of the nested data structures would be when I actually wanted the smaller data structure for something else, like a parameter for a procedure that only handled some small part of the data.
