Ok, here's a simple question to help flesh out what you are saying. US patent 4558302 (LZW compression) is pretty old and easy to find online. Its figures do include some code listings, though if they didn't I don't think that would change anything. It is definitely not a patent of any particular software package; it is a patent on the algorithm.

Is it, in your view, a software patent?
I don't know. Remember, I'm the guy who says he doesn't know what the term "software patent" means.
Incidentally, though I have only a passing familiarity with patents, ISTR there is stuff in an application besides claims, like stuff that demonstrates the invention is actually complete and useful, so drawings and code listings might be in there without being part of the claims.

nothing in a patent is required to be 'useful'

One thing I do remember from a class long ago is the three pillars of
patentability: the invention must be new, useful, and nonobvious. I
just googled that phrase to make sure I hadn't fabricated it in my mind
over the years, and I got a bunch of hits.

dlang a patent does have to be useful, at least in the US which may not be where you are based.

in theory you are correct, but in theory it must also be novel and non-obvious.
in practice, the person applying for a patent doesn't even have to prove that the idea works (no working models required)
