LDX $08 ; <= I GET A SYNTAX ERROR HERE!!!
You need to learn the different addressing modes. I had a similar problem
when I started out. What you are trying to do is load X immediate and what
you are doing is loading X abolute-zeropage. I don't know why you'd get a
DASM syntax error per se, but your program won't run the way you think it
should. Immediate in DASM has to be specified with the # symbol.
LDX #$08
What is confusing, perhaps, is thinking that # means hex. It does in HTML,
but it doesn't here.
Number formats in DASM are decimal by default (no preceding symbol), $ hex,
and % binary.
; LOAD THE NUMBER 8 (immediate)
LDX #8 <- decimal, confusing to me because of my HTML background.
LDX #$08 <- hexadecimal
LDX #%00001000 <- binary
; LOAD THE CONTENTS OF MEMORY ADDRESS 8 (absolute, zero page)
LDX 8 <- decimal
LDX $08 <- hexadecimal
LDX %00001000 <- binary
; LOAD THE CONTENTS OF MEMORY ADDRESS 8 (absolute)
LDX.w 8 <- DASM forced word, decimal
LDX.w $08 <- DASM forced word, hexadecimal
LDX.w %00001000 <- DASM forced word, binary
LDX $0008 <- standard hexadecimal notation
