Instead of packing some things ("chars") into words for C to access on a byte per byte basis

He's not packing "chars". He's packing integers (note the 'I*' pack template). And whilst his sample code shows him just incrementing those integers (which he is initialising to 0), his description points out that he intends to populate the structure with "scores", which he is presumably obtaining from somehwere where they must be accessed via C.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
