I heard, but only rumor, that Forth2006 will have a gosub literal.
(Reminds me of a Computer Language (mag) cover page joke from way
back, I'd guess April 86. As I remember, all its April mags were
80% jokes, but convincing enough to pass the smell test.)

How quickly I forget! (and how unfortunately often). I figured out the
other day that I actually spent more time programming Fortran before
1970 than I have C since. I try to work in Forth.

Should any political party attempt to abolish Social Security,
unemployment insurance, and eliminate labor laws and farm programs,
you would not hear of that party again in our political history.
There is a tiny splinter group, of course, that believes that you can
do these things. Among them are a few Texas oil millionaires, and an
occasional politician or businessman from other areas. Their number
is negligible, and they are stupid.

Just that obscure C (and C++) language! :-)

It's a real issue, and the meaning of "plain text" is no longer clear.
For instance, some but not all can read x� as x^2 (or x**2). The
character '�' is $82, but characters above 7F aren't standard and may
differ from font to font. Is '�' plain text or not?

Randy: I don't know what you mean by "pure text" in this context. '^' is
ASCII character 5E, called "circumflex" and often used as a caret. It is
the standard exponentiation symbol in some programming languages, as
'**' is in others (Fortran et. al.). I have no particular preference for
either usage, but '^' is more common in news posts. It seems that Jean
would have used it if it had been available to him. '**' is rare enough
so he thought it needed explanation.
Glen: What language uses '^' to mean XOR? What have I forgotten?

Oops. Misidentified the issue here. I was thinking that someone was
giving a sequence for typesetting a superscript on certain terminals.

If simply typing the circumflex key followed by anything but a vowel
doesn't work for you, try putting a space "under" it.

What's non-plain-text about 0x5E?

I concur. Let's keep usenet pure text. The world has already screwed
up email by resorting to every variant of HTML/RTF/blah blah blah
format known to man.

You are right: I did not make my �copy and paste� correctly.
How dumb of me! I just realized that my error was not in the
calculation of the partial fractions but in taking the inverse
Z-transform from the partial fractions! I am red-faced.
I thank you very much for answering.
