Addressing arrays __asm lda array[1];

Should be a simple one ( i think)

static char Array[10];

void main(void){
__asm lda Array[1]; //Cannot get this one line to work? error C18123
}

Hello and welcome to the forum.

For inline assembly use the instruction should take the following form:

__asm lda Array:1;

However, within a "normal" assembly program, the equivalent instruction would be -

lda Array+1

Thanks, will try that. (I think i did try that, i tried many things, most obviously Array+1 with diffrent brackets).

Can I ask where specifically in the help files that was, or how it was interprated from the help files?

Hello,

I am not sure of the device you are targeting - I assume it might be the HC(S)08.

Within your CW installation, there should be a manual for the compiler, e.g Compiler_HC08.pdf. Within this manual there likely to be a section headed "High Level Inline Assembler". Also may be of interest, within the section "ANSI-C Frontend", a sub-section headed "Defining C Macros containing HLI assembler code".

Regards,

Mac

Thanks, that worked!

I guess the answer is in this?
