### Macros
|
|
|
|
@todo macros are meta-code that is executed by the compiler, in a preprecessing step
|
|
during the compilation, and can produce output that is then replaced on that point in the input source.
|
|
Allows us to create pre calculated sine tables and such.

Memory Block Operations
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
@todo matrix,list,string memory block operations:
|
|
|
|
- matrix type operations (whole matrix, per row, per column, individual row/column)
|
|
operations: set, get, copy (from another matrix with the same dimensions, or list with same length),
|
|
shift-N (up, down, left, right, and diagonals, meant for scrolling)
|
|
rotate-N (up, down, left, right, and diagonals, meant for scrolling)
|
|
clear (set whole matrix to the given value, default 0)
|
|
|
|
- list operations (whole list, individual element)
|
|
operations: set, get, copy (from another list with the same length), shift-N(left,right), rotate-N(left,right)
|
|
clear (set whole list to the given value, default 0)
|
|
|
|
- list and matrix operations ofcourse work identical on vars and on memory mapped vars of these types.
|
|
|
|
- strings: identical operations as on lists.
|
|
|
|
- matrix with row-interleave can only be a memory mapped variable and can be used to directly
|
|
access a rectangular area within another piece of memory - such as a rectangle on the (character) screen
|
|
|
|
these should call (or emit inline) optimized pieces of assembly code, so they run as fast as possible

Bitmap Definition (for Sprites and Characters)
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
to define CHARACTERS (8x8 monochrome or 4x8 multicolor = 8 bytes)
|
|
--> PLACE in memory on correct address (???k aligned)
|
|
|
|
and SPRITES (24x21 monochrome or 12x21 multicolor = 63 bytes)
|
|
--> PLACE in memory on correct address (base+sprite pointer, 64-byte aligned)
|
|
