DVIasm is a TeX utility program that is designed for editing DVI les with three steps: disassembling, editing, and assembling.

The rst stage of DVIasm [1] supported the standard DVI fi le format as in DVItype and DTL, but in a much more exible way than those utilities. In the second stage [2], DVIasm made it possible to handle two-byte characters, CJK and Unicode characters. The extended DVI formats generated by Omega, Japanese pTeX were all supported, as well as ordinary LaTeX packages with subfont scheme such as CJK-LaTeX and Korean ko.TeX. The final stage of DVIasm confronts the two advanced TeX engines, LuaTeX and XeTeX, both of which can handle OpenType and TrueType les in a direct way without TFM files.

In this talk we introduce DVIasm with a few interesting applications to the TeX world, and discuss how DVIasm handles the extended DVI formats generated by LuaTeX and XeTeX.
