HC05 assembly conversion to HC08

baddad — Thu, 31 Aug 2006 23:59:26 GMT

I'm helping to convert an old HC05 project to HC08 using CW v5.1.

This statement shows up as an invalid addressing mode:

LDA #"U"

I haven't been able to find the proper way to write this.

Any suggestions on what I can try?

Thanks,

Brian

Brian -

I don't know why the double quotes (LDA #"U") didn't work. But I tried with single quotes (LDA #'U') and it worked correctly.

Interestly, this use of the double quotes for the string constant did work (and is another work around):

U: EQU "U"

LDA #U

Thanks, I'll give it a try.

Seems to be a strange assembler response, because LDA #"d" works...

Thanks again.
