Can anyone identify this peculiar 67/97 program?

[Dave Britten]

I bought some more used-but-blank mag cards from ebay (I don't have a problem, I can quit whenever I want), and among them was one card with no markings but clipped corners. Intrigued, I checked it with VER on my 41, and it reported a 67 program on both sides. So I fed it into my 97 and printed the listing. The card read fine first try on both calcs, so I don't think we're looking at any corruption here - the checksum would have caught that anyway. But I can't tell if I'm looking at the incoherent ramblings of a madman, or if there's some meaning here. What's going on with all the flag setting and clearing???
