Hello all,
I am writing a thesis using the following code:







\usepackage{amsmath, amsthm, amssymb}




\title{ }

\author{ }

\dept{ }


\typein[\files]{Now put in includeonly}




















I am trying to process only chapter 2, but I am getting all sorts of 
error messages that, as far as I can tell, are associated with not 
having a \begin{document} command at the beginning of my file. For 
instance, the beginning of the .log file shows:

This is pdfeTeX, Version 3.141592-1.21a-2.2 (MiKTeX 2.4) (preloaded 
format=latex 2006.12.28) 19 JAN 2007 14:08

spelling (e.g., `I\hbox'). Otherwise just continue,

and I'll forget about whatever was undefined.

! LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.

Type H <return> for immediate help.

You're in trouble here. Try typing <return> to proceed.

If that doesn't work, type X <return> to quit.

Missing character: There is no A in font nullfont!

A later error shown by the .log file:

! LaTeX Error: The font size command \normalsize is not defined:

there is probably something wrong with the class file.

Since I am a newbie, I am having trouble solving this. Maybe these 
errors have different sources after all? I googled “font nullfont”, 
searched the FAQs, and read many of the errors explained there. I tried 
erasing all the \include commands after \begin{document} thinking they 
may conflict with what I am entering at the prompt. But obviously I need 
them because otherwise LaTeX is not even creating the .aux file (if I 
understand correctly). So, I’ve run out of ideas. If somebody could find 
the time to sketch a solution or point at where to find one, I’d be very
