But in order to be funny doesn't it usually have to
be true?...I've actually known several ravishingly
beautiful blond female programmers/computer scientists,
and frankly, they were AT WORST just the usual fakes
but with a better disposition than the phlegm-encrusted
doughboys who generally occupy the position...they
weren't stupid and they were pretty nice people
overall, so what's the joke?

Stripped is sexier.

No, signs are not "punctuation".

It is common to collapse this distinction temporarily in teaching.

You don't know what he knows.

Translation: it is correct.

Don't speak for the newbie. You're not a newbie. How would you know
what the knewbie kneeds to know?
But strangely, knor are you an experienced as opposed to corrupted
programmer. These sorts of corrupted and incompetent programmers love
to speak for the newbie.
English cannot be used as a formal metalanguage for C, therefore
anything that is said in English about C (such as what's set when end
is set) can be interpreted as wrong by hostile dweebs.
We now kneed you to blank or remove C: the Complete Nonsense. You
could do this silly set of silly operations on the example code of any
computer book, and we have learned that you produce code that is far
less competent. We're tired of you wasting bandwidth and patience.

And can be used by kooks to interpret it as correct:

"We"?
And "wasting bandwidth": Until you started this a few months ago,
Seebach had NEVER MENTIONED SCHILDT here for at least 7 years that I
can see. And he has only responded to a small proportion of your
provocations.
Anyway, we're all waiting for you to "take this to the next level".
(Well, here "we" could just mean me, I must admit.)
What would that be? A Gandhi-style "fast unto death" unless the page
is removed? A PETA-style naked picketing of Seebs' workplace? Mailing
packets of brown powder to Jimmy Wales with "The next one will be
anthrax unless you withdraw the Schildt page."? Or just blurting out
hundreds of posts here of psychotic rants?
My bet is on the latter.

So you'd not want your variables in registers? Why on earth not?

My thanks and appreciation to everyone who replied (most
did by email). I'm still on my old service but the
cutoff date for that is April 7 (ie, today in most parts
of the world, including here soon). Now for trying to
get a new service working....
