For yonks I've been seeing "XXX" as a flag to mean "needs more
work" or
"look at this carefully, just in case" etc, and I use it myself.
Whence did it come about? I think I saw it as early as PWB, but can't be
sure.

The earliest my quick grep could find was 4.0BSD. I didn't find it in this
sense in pwb, but it was a quick grep...
xxx is used extensively in prior versions, but there it's meaning is
'placeholder' or 'don't care'. Mostly for /tmp/XXXX files, but
also for
things like Jxxx handles all the jump commands or dates of the form 24 Feb
XXXX or stuff like that.

I'll also add that this seemed foreign when I had patches that had XXX in
them I submitted to the linux folks in the early 90s. It was second nature
in the BSD side of things. But I don't know if that's a Berkeley thing or a
Bell Labs thing Berkeley picked up...

My guess is that this was invented independently several times. I think
I used it myself in the 70's (and not on UNIX), as soon as I had a text
editor, because "XXX" was easy to search for and was not going to
overlap with variable names, etc.
There's a discussion here:

I use "EOW" when I'm iterating through something, and stop partway

combination anywhere else. (It's not random: it stands for "End of WIP")
I use "XXX" too - usually in the form "XXX FIXME".

Timing is everything, especially in humour...
I nearly choked on something when I realized this thread was going on as I
read notes on the PostgreSQL list where the somewhat famous (?) Tom Lane
observed that he was planning to comment a commit to password management
code with "XXX FIXME"
:-) :-) :-)
So this is clearly an idiom still in active use!!!

Me too, for the same reason: the code is tricky or subtle or needs fixing.
It does tend to make my students raise their eyebrows; perhaps they have
their nanny filters turned on :-)
