[comp.text.tex] Help: Specifying Font Size

sommer@BINAH.CC.BRANDEIS.EDU (08/11/90)

For most of my documents, I require a fairly big preamble wherein I
define all sorts of things, especially journal abbreviations, so for
convenience and to conserve disk space I store preamble.tex in an out
of the way directory.

%%% preamble.tex
\documentstyle[several style options]{article}
\newcommands ....
\newenvironments ...
...
%%% \begin{document} 

This way, I just begin my papers with

\input{preamble}
% only a few more article-specific preamble items
\begin{document}
This is my text ...

The most common ``problem'' I have is wanting to change between 10,
11, and 12 pt options, in order to get the biggest font on the fewest
pages. (I LaTeX in each font size and read the log file for number of
pages -- e.g., if 10pt --> 6 pages, 11pt --> 6, 12pt --> 7, I will
usually print out the 11pt document.) This tends to produce a last
page with the ``fullest'' appearance.

Using the \input{preamble} approach, IS THERE SOME EASY WAY TO
SPECIFY 10, 11, 12 PT style options OUTSIDE OF THE
\documentstyle[options] line so I can include it in the specific
file.

\input{preamble}
% SOME COMMAND TO SPECIfY 10, 11 or 12 pt FONT 
\begin{document} 

Maybe somebody will recommend using a magstep command (I'm mostly a
LaTeXer, not a TeXer!!). Will that properly scale _everything_ and
_identically_ reproduce output from previous runs using [12pt] as a
genuine style option? Other ideas?

Thanks in advance for your help and suggestions.
