Hi,

Re: files in attachment

Why is step 3 typeset in chapter 2's first paragraph instead of chapter 1's
first paragraph and how to correct ?

I still say it's not a very good idea to do this but here is a fixed
version of your macros. You should always take care to keep scratch
counters/dimenens/... local.

\def\doCountLines#1\par{%
	\begingroup
	\setbox\scratchbox\vbox{#1\par}%
	\getnoflines{\htdp\scratchbox}%
	\global\parlines=\number\numexpr\noflines
	(step 2: P\space\the\parnumber, \the\parlines\space L)\relax
	\ifnum \parlines = 1
		(step 3: P\space \the\parnumber, \the\parlines\space L)%
	\fi
	\endgroup#1\par}

\def\CountLines{%
	\global\parnumber=0
	\EveryPar{%
		\advance\parnumber by 1
%		(step 1: P\space\the\parnumber, \the\parlines\space L)
		\ifnum \parnumber = 1
			\expandafter\doCountLines
		\fi}}

I apologize for my ignorance, I'm still confused with this one (see
attachments)...

What is it about it that it's a bad idea ?

code:

\ifnum \parlines = 1
   (step 3: P\space \the\parnumber, \the\parlines\space L)%

Who knows, it could work or fail in a few cases.

Thanks Wolfgang.

Digging into some TeX books to understand how and why these fixes work...
