The way I see it, the execution would be step 1, 2, then, since g X<>Y is false, step 5 is next then, since g X>Y is false, step 8 is next just putting a 1 in the display and not going anywhere. What have I misunderstood?

"g X<>Y" is not a test, it is simply exchange X and Y registers ( [g] [7] on an HP-65)

Ah! That explains all. I wasn't familiar with the notation. Thanks!
