Now you've done it!  I feel that insatiable sense of curiousity
creeping up on me again!

Please forgive me.  I know this doesn't really belong in comp.std.c++,
but...

Has anybody other than me ever wondered: What's the oldest line of
code in existance (in source form) that is still in production use?
(For the sake of argument, let's define `production use' as regular
use with a frequency of no less that one time each year.)

Anybody got any clues to this Software Archeological mystery?  Perhaps
I should start a serious expedition.  I can see it now. Dr. Leaky, Jean
Sammett, and I, out there wandering the open savanas and (White?) plains,
occasionally descending deep gorges... descending back over countless
zillions of milliseconds... in search of the One True `missing link' of
the software world... the oldest living specimen of an original line of
code.

As any historian will tell you, we can't know where we are going if we
don't know where we have been.  How can we know how long the code we
write today may last if we are not even sure how long code has lasted
up until now?

	Do we build a house forever?

Seriously, if anybody knows of very ancient lines of (unmodified and
unmaintained) code that are still in production use, please send me
some E-mail about it.  After a couple of weeks, I'll post a follow-up
to comp.compilers describing/announcing the oldest reported line.

My legendary modesty prevents me from accepting this compliment,
but thanks anyway. :-) :-)

Actually, Roland McGrath made that (perfectly correct) observation.

I was responsible for that comment though.

Yes.  Now if we can just get the Big and Little Endians to crack their
eggs from the same end, all we'll have left to do is to teach the Arabs
not to covet thy neighbor's shipping ports, gold, crude, ...
