personally, for each external service (say a courier service), I have a single *_H include file with all the structure DS definitions (templates data type *_t), constants, prototypes, it contains all pure defs pertaining to the specific external service.Easy to find, clear to all , modular, the linker will just link what it is needed in the final PGMs.Use in such _H conditional compilation to avoid including it twice.if using service programs and not just dynamic PGMs, add to the bottom of the export keeping the same sig, you ll be fine.

I have a question related to the copy source associated with a service program I have for communicating with Amazon SP-API. I've had this service pgm for quite a while for managing merchant fulfilled orders.
I recently was asked to add the ability to get(buy) shipping labels. I debated whether to create a standalone program vs. creating a separate service program vs. adding a procedure or two to the existing service program.
Because the authentication and base URLs are the same (and the new procedure would be called from multiple programs), I decided to add it to the existing service program.
Now, I'm wondering about the /copy source. For better/worse it contains a lot of named constants, defined values (templates), and exported procedures that wouldn't be necessary (or relevant) in programs that call this new procedure.
So my question... do I just add the new prototypes to the existing service program /copy source, OR should I create a second /copy source containing JUST the prototypes necessary (two of them) for the other programs. Is that "OK" to do, or is it frowned upon? I'm thinking about complexity, conflict of named constants, procedure names (no prefix), etc.
Thoughts?
