How to work with TeX/LaTeX documents in TEA? First of all, set up Preferences > Commands > LaTeX options. They are good by default, but check them. And DO NOT add the &-character after the command lines. Of course you must have all that LaTeX stuff installed.
To make dvi-file from the current LaTeX/TeX document, use Process with LaTeX function and see to Logmemo for errors. If all right, now you can convert dvi to ps or PDF. Use dvi to PS or dvi to PDF functions. TEA saves all dvi's and resulting files into the directory where your TeX document is saved. TEA cares about their filenames, don't think about it.
To view a dvi-file, use View dvi menu item. To view PostScript and PDF files, use View PS and View PDF functions.
So the usual way to produce PDF from LaTeX with TEA is: Process with LaTeX, then dvi to PDF, then View PDF to view the result.
Or, alternatively, if you have pdflatex installed, use Process with pdflatex and then View PDF.
