Sorry, I trimmed my original message so it didn't seem like I was trying to 
shoot you down on your assembly tips.  I used to do tricks like these back 
in the early 80's when I was hand-assembling all of my 6809 projects.  No 
point missed, just adding a comment or two, that's all.  Keep up the tutorials.
