@ -103,10 +103,7 @@ Raw labels are inserted directly into bytecode.
|
|||
Absolute labels are double quantities.
|
||||
Relative labels are single signed byte quantities with a ±127 range.
|
||||
|
||||
The zero page (`#00XX`) is used for system devices, along other things.
|
||||
It's common to see labels such as `.System/vector`, being a reference to the address `#0000` packed into just `#00`
|
||||
However as UXN has a special `LDZ` operation for loading from the zero page, this address can be specified as simply `#96` to save a byte.
|
||||
As the last device is mapped to `#CX`, it is common to see `#DX`, `#EX` and `#FX` used for program-global variables for ease of access.
|
||||
The zero page (`#00XX`) is used for program globals and convenient scratch space.
|
||||
|
||||
Literal byte relative references ala `,foo` are used for control flow.
|
||||
Using only a single byte, these references have a range of ±127 instructions.
