Core words
|
||||
|
||||
This section contains arch-independent core words of Collapse
|
||||
OS. Those words are written in a way that make them entirely
|
||||
cross-compilable (see B260). When building Collapse OS, these
|
||||
words come right after the boot binary (B280).
|
||||
|
||||
Because this unit is designed to be cross-compiled, things are
|
||||
a little weird. It is compiling in the context of a full
|
||||
Forth interpreter with all bells and whistles (and z80
|
||||
assembler), but it has to obey strict rules:
|
||||
|
||||
1. Although it cannot compile a word that isn't defined yet,
|
||||
it can still execute an immediate from the host system.

2. Immediate words that have been cross compiled *cannot* be
|
||||
used. Only immediates from the host system can be used.
|
||||
3. If an immediate word compiles words, it can only be words
|
||||
that are part of the stable ABI.
|
||||
|
||||
All of this is because when cross compiling, all atom ref-
|
||||
erences are offsetted to the target system and are thus
|
||||
unusable directly. For the same reason, any reference to a word
|
||||
in the host system will obviously be wrong in the target
|
||||
system. More details in B260.

This unit is loaded in two "low" and "high" parts. The low part
|
||||
is the biggest chunk and has the most definitions. The high
|
||||
part is the "sensitive" chunk and contains "LITN", ":" and ";"
|
||||
definitions which, once defined, kind of make any more defs
|
||||
impossible.
|
||||
|
||||
The gap between these 2 parts is the ideal place to put device
|
||||
driver code. Load the low part with "353 LOAD", the high part
|
||||
with "380 LOAD"
