After we've loaded the high part of the core words, we're at
|
||
|
|
the "wrapping up" part. We add what we call a "hook word" (an
|
||
|
|
empty word with a single letter name) which doesn't cost us
|
||
|
|
much and can be very useful if we need to augment the binary
|
||
|
|
with more words, and at that point we have our future boot
|
||
|
|
CURRENT, which PC yields. That is why we write it to the
|
||
|
|
LATEST field of the stable ABI: This value will be used at
|
||
|
|
boot.
|
||
|
|
|
||
|
|
After the last word of the dictionary comes the "source init"
|
||
|
|
part. The boot sequence is designed to interpret whatever comes
|
||
|
|
after LATEST as Forth source, and this, until it reads ASCII
|
||
|
|
EOT character (4). This is generally used for driver init.

Good luck!
