these identify an area of your program as data. you can access these
references by a label in front of them.
ex.
getHighScore:
ld hl,myHighScore
ld a,(hl) ; a=99
; or you can even do...
ld a,(getHighScore) ; this is legal. you would get the first
byte of the OPCODE "ld hl,XXXX"
...
myHighScore: .db 99
.db is 1 byte, or 8 bit
.dw is 2 bytes, or 16 bit
.ds <xxxxx> is xxxxx bytes of space.
