hello,
i'm trying to learn 6502 asm. here is a part I don't understand:
B EPZ $6 ; low part of adr
BH EPZ $7 ; high part of adr
...
LDA (B,X)
looking at the first two lines, I can think that the adr is $706.
but the assembly code for LDA (B,X) is A1 06 meaning that only low part of
the adress is used, pointing to page zero.
any idea?
guillaume.
