The error message I get is:
Now, I use TeXShop and change my output to TeX and DVI, not pdfTeX. Is there a way to include both simultaneously? Any help is appreciated.! LaTeX Error: File `example3' not found.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
