Syntax

Datablocks

Addressing is different for non-primitive and primitive types.

The general syntax for addressing primitive values in a Datablock is

%DB{db-number}.DB{bit-length-code}{byte-offset}(.{bit-offset})?

...

db-number: number of datablock
bit-length-code:
	X - 1 bit
	B - 8 bit / 1 byte
	W - 16 bit / 2 byte
	D - 32 bit / 4 byte
byte-offset: offset in byte to start of data block
bit-offset: offset in bit to start of bit

For non primitive objects the (pointer?) notation from TIA is used which is

P#DB{db-number}.DBX{byte-offset}.{bit-offset}
Note, here, bit offset is not optional but usually always 0

The parts are:
