There's only 2 operands to print in these cases.

Looking good though with the latest changes :)

Thanks, fixed on 1.29 branch

Closing as fixed...

Sheesh, don't be sad on AtariAge about the swpb issue, seems to me you worked out the bool postByteSwap flag which if true means you just need "mov" before it, else you need "movb" without it. I.E. never make sense to do movb+swpb.

Thanks. Yep, exactly right, I figured that out after I saw this but thanks anyway.

Only sad it be seeing yet another regression :-) Working on this compiler is always 2 steps forward 1 step backwards but we'll get there.
