And presumably that is the origin of XYZZY in Colossal Cave Adventure!

Sounds like a magic cookie.  Obscure, but still vulnerable.

I learned two things early in my career:

1. Magic cookies are Evil.

2. "Never" (as in "Oh, that'll never happen") is usually about 6 months.

I once came across a little executable called XYZZY.
Whenever you ran it, it said, "Nothing happens."

Should it say "Nothing happens here.", or is that what the program 
"Hello-Sailor" says???

I have these two lines in my .profile:

alias xyzzy="echo Nothing happens."
alias plugh="echo You'''re at end of road again."

In the Colossal Cave Adventure game, "plugh" does *not* put you at the end 
of the road.  "Plugh" moves you between the well house and Y2.

The burroughs compiler group was in southern california.   As is:

https://en.wikipedia.org/wiki/Zzyzx,_California

Which I suspect was the origin of the name in the Fortran compiler.

Everyone driving to vegas from la sees the zzyzx rd sign.

ISTM that there are many stories concerning the origin of XYZZY.  See:
