System variables
|

|
|
|

|
|
There are some core variables in the core system that are
|
||
|
|
referred to directly by their address in memory throughout the
|
||
|
|
code. The place where they live is configurable by the RAMSTART
|
||
|
|
constant in conf.fs, but their relative offset is not. In fact,
|
||
|
|
they're mostly referred to directly as their numerical offset
|
||
|
|
along with a comment indicating what this offset refers to.

This system is a bit fragile because every time we change those
|
||
|
|
offsets, we have to be careful to adjust all system variables
|
||
|
|
offsets, but thankfully, there aren't many system variables.
|
||
|
|
Here's a list of them:
