Thanks for taking a look.

The binary is the source, per se. The author hand-wrote x86_64 opcodes in hex,
which is what dmp.txt contains. This is "compiled" by using xxd to write those
bytes out to a file. Then system.fs is just a blob of Forth source that gets
appended to the binary.

It's kind of magical that this scheme works at all, but that's Forth for ya.

Ah, nice. Thanks. Will do.

Perfect. I didn't realize we had such a field. Thanks!
