Writing a bytecode interpreter (for TeX dvi files)

[Jonathan Fine]

I'm writing some routines for handling dvi files.
In case you didn't know, these are TeX's typeset output.

These are binary files containing opcodes.
I wish to write one or more dvi opcode interpreters.

Are there any tools or good examples to follow for
writing a bytecode interpreter?

I am already aware of opcode.py and other modules in
Python Language Services, in the Library Reference.

Thanks.
