I have defind:

MOTOROLA

RAM1: SET1 DS.W 1

RAM0: END_RAM0 EQU $1E

the following statement should get the Index for read the high byte of

SET1 in a subroutine.

CODE:

ld Y,#{SET1-END_RAM0} ;{} = Index, 8-Bit

ASM-Message:

Error 54: Can't match Addressing mode 'ld Y,#{SET1-END_RAM0} ;'

Subroutine:

sub A,({END_RAM0+1},Y) ;8-Bit-Addr.(=$1f) + 8-Bit-Offset

this line is correct in ASM Subr. obj-code is 90 E0 00

can sombody help me?

regars

Hi Habluetzel,

With the following declarations,

segment byte at 80-FF 'ram0'

.SET1 DS.W 1

.END_RAM0 EQU $1E

and with the same instruction

ld Y,#{SET1-END_RAM0} ;{} = Index, 8-Bit

my assembler does not producing any error. I think there is a declaration error in your program. I could not clearly understand what is RAM1: & RAM0: in your code.

Could you reply?
