This is one of many jokes and humorous articles I collected, mainly from USENET and similar
sources in the early to mid 1990s. They're really not very interesting nowadays.

Since no one seems to be able to come up with a definitive list, here is
one that hangs around on our machines. I have no idea of the origin and
could not hope to trace it. The first (long) block is the 'original'
set that we have and the others are later additions. I'm slighty
surprised tho find that it doesn't seem to have BBW - branch both ways.
Share and enjoy!

Two that I have wanted on occasion in the past:
XOI eXecute Operator Immediately
XOS eXecute Operator Slowly (and painfully... :-)

P.S. If any real operators are reading this, remember: :-) :-) :-)
(No, I don't want to start a thread on Real Operators (tm))

well as variations on the theme...
BBL Branch on Burned-out Light
DWIM Do What I Mean
HCF Halt and Catch Fire (yes, I really saw it!)
IDM Invert Dot Matrix
JRL Jump to Random Location
RWD ReWind Disk
XOP eXecute OPerator
