What exactly do you mean by "splitting up a line of a script". The basic
unit of a Perl program is not a line but a statement. Actually perl doesn't
even know or care about lines (well, except for the running line counter, of
course).

That is not surprising because lines are irrelevant to Perl's syntax and
therefore of course are not mentioned anywhere in the syntax definition.
Perl does not care if a program is written in 50 short lines or in 5 very
long lines.

I have no idea what a .7 line, a .2 statement or a .8 statement is supposed
to be.

splitting a line

One of my goals for last night's reading was to figure out how to split up a
line of a script. I have syntax confusion on this point, not helped by
being unable to find anything on it in the camel book.

In fortran you put ampersand at the end of line .3 and at the beginning of
line .7:
statement .2 &
& statement .8

Since perl has semicolons at the end of statements, this would be:

statement .2 &;
& statement .8;

Is there a zeroeth order substittution to make the above
syntactically-correct perl?

That's great and very considerate of you.
Unfortunately it still doesn't explain what a .3 line, a .7 line, and a .2
statement are supposed to be.

As far as Perl and perl are concerned there are no lines in a Perl script(*)
at all. It's like asking how many inches are in a cup of sugar. Yeah, there
are ways to measure the hight of the sugar, but the baking recipie doesn't
care because it measures in cups.

Lines are useful organizational aides for human readability and nobody
should dismiss their importance.
So just use them to structure the optical layout of your program text such
that it is the easiest to read. "perldoc perlstyle" has some good
recommendations.

(*) Please note, I'm assuming you are talking about the programming language
Perl and scripts written in this language. Perlscript does exist, too, and
it is quite a different animal.

Perl is sooo different from fortran.

I don't like exceeding 65.

If there were--and it sounds like there really is only one line in a
perlscript--
one line in a perlscript
, how would I put it on usenet without making huge errors?

Duh, then you should read the std docs regarding Perl's syntax.

The 2nd paragraph in

perldoc perlsyn


Perl is a free-form language, you can format and indent it
however you like.

Perl (nor perl) has semicolons at the end of statements.

Perl has semicolons *between* statements.

Many other programming languages use semicolon as a "statement terminator",
Perl however uses semicolons as a "statement separator".

I would say that "fundamentally" there are no lines. Consider e.g.
comments, regexen, literal strings.

Fair enough. You are right, there are some tokens where line breaks are
significant.

Pick up a copy of "Perl Best Practices" http://www.oreilly.com/catalog/perlbp/
Chapter 2 (Code Layout) directly answers your question along with any
