that application was only required to read. The main technique was to have a pgm described file with a wide/long buffer.

Yup, that's exactly how it works (and it works just as well for writing as it does for reading), and since we have an alternate source of meta-data (and given that it's a server program, and that it's the client that needs that meta-data), it works really well, and it saved us having to recompile the "family jewels" for every customer environment.

But now, I've been asked to research extending that so that (strictly on a read-only basis, and only for certain files) we can tie directly into "native system" data, rather than slaving fields in our files to those in the native system's files.
