0.6-PRE

-------
|

* Added `routine` and `vector` types, and `copy` instruction.

For 0.6:
|
||||
|
||||
* `interrupt` routines.
|
||||
* `vector` type.
|
||||
* `with sei` blocks.
|
||||
* `copy` instruction.
|
||||
* `goto` (tail call).
|
||||
* `vector` type... with declared `inputs` `outputs` `trashes`?
|
||||
* `copy` instruction... that can copy a constant to a user-def mem loc.
|
||||
* A more involved demo for the C64 — one that sets up an interrupt.
|
||||
|
||||
For 0.7:
|
||||
|
||||
* `word` type.
|
||||
* `trash` instruction.
|
||||
* zero-page memory locations.
|
||||
* indirect addressing.
