A case against the x<>y key

[Paul Dale]

I knew it could be done on a four level stack, just not strictly left to right. The final term can be evaluated as 6 7 / 45 x<>y y^x but that isn't left to right and uses the x<>y operation which this thread is about.

Interestingly, on the original HP 35 this would become 6 7 / 45 y^x saving a keystroke and not using x<>y.
