Here is a raw dump of the TeX program. Eventually I will try to make it easier to read, cross-reference against corresponding code sections in other versions/programs, etc.

Please see previous page for some ways you can prepare to read this. In particular, taking a look at these programs may help: POOLTYPE, TANGLE, DVITYPE.

Note: This page takes a long time to load fully, and may download about 60 megabytes.

To read the program, click on "Fetch modules" below.

That's the end of this page. If you have any feedback about anything on this site, you can contact me here. To go back to the top-level page (if you are not on it already), click here.
