HP12C x><y Key

[rprosperi]

They are not the same:

Unshifted: This swaps the X and Y registers

g-shifted: This is a conditional test, used in programs. It does the test "If X is less than or equal to Y is true then continue with the next instruction; if not true, the skip the next instruction and continue with the following one".

The labels simply look similar but if you look closely, you'll see the difference.
