It is more difficult than necessary to do it this way. If you follow
Phil's advice and try to understand how TeX works internally, you'll
see that there are some quite nasty things. An "f" is not just an "f"
in TeX. Look for "\catcode" in TeX by Topics.
The "f" in "first" you typed has \catcode 11 while the "f" returned by
\jobname has \catcode 12.
A very simple solution is this:
Remove the \documentclass stuff completely from the file. Assume this
file is called paper.tex.
Then prepare other files:
paper-first.tex:
_________________________________
\documentclass[first]{...}
\input{paper}
_________________________________
paper-second.tex:
_________________________________
\documentclass[second]{...}
\input{paper}
_________________________________
paper-printversion.tex:
_________________________________
\documentclass[third]{...}
\usepackage[monochrome]{color}
\input{paper}
_________________________________
The main advantage of this approach is that it is easy to understand,
even in a few years. And it's clean LaTeX.
Regards,
Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
