||
|
||
* `byte nullchar_scr` – the null terminator for strings in the screen encoding, equivalent to `""scrz[0]`, can be overriden by the `NULLCHAR_SCR` feature
|
||
|
||
* `null$ nullptr` – the invalid pointer value; the value of the `NULLPTR` feature
|
||
|
||
* `bool true`, `bool false` – boolean constants
