DAIRFAIL was available in the 1980s; I don't recall whether it was available in the late 1970s, and bitsavers doesn't have the manuals I would need to check.

Seems like that was pretty common at the time (1990's?) because I remember multiple times having to go to the programming manual to find the SVC99 codes. There were a few (1708?) that I knew without having to look them up.
