C Programming Style -- New thought ("writing code")

Yes.  I prefer to, because it matches the way I think better.  However, this
(I feel) *increases* my desire for terseness.  Additionally, once I have typed
something in, I am more comfortable staring at hardcopy that a terminal
screen.  But once again, the more that is packed onto the page READABLY, the
better I like the code (and remember, you can't run GREP(1) on paper (yet)).

As an example:  the recent BYTE article on the TRAVESTY program (a few months
back) included a PASCAL program with a doubly nested loop, which had to use
a logical variable to escape from the inner one (I believe that that required
a double test in the while).  I recoded it in C, and came up with half the
number of lines, SIMPLIFIED IT TO A SINGLE LOOP using "C ``tricks''", and
came up with what I felt was vastly more readable code:  the whole function
"fit in my mind" at once.

The PASCAL program was not necessarily badly written; it was probably textbook
quality (not saying much :-).  However, readability is in the eye, and the
mind, of the beholder.

Who would you rather listen to, someone who gives an hour-long speech in
the 1000-word Basic English subset, or someone who uses the full power of
English to eloquently say the same thing in 5 minutes (without using archaic
words not in use for 300 years, note)?
