The assembler recognizes four different kinds of text lines:
A blank line (ignored)
A label: a single word/number ending with a ":"
A directive: a line beginning with a "."
Everything else is a line of assembly opcodes
Comments
LD A,5 ; Five rows per object
Everything after a ";" on a line is ignored as a comment. Lines that begin
with a ";" are seen as blank lines (ignored).
Includes
.include hardware.asm
Key/Value Constants
._CPU = Z80
.CONST_A = 0x20
KEY = VALUE pairs. Keys that begin with "_" are meant for the assembler.
