Reviewing the stackR(Roll Down)

The 9(roll down) key lets you review the entire contents of the stack by "rolling" the contents downward, one register at a time. You can see each number when it enters the X–register.

Suppose the stack is filled with 1, 2, 3, 4 (press 1 š2 š3

š4. Pressing 9four times rolls the numbers all the way around and back to where they started:

What was in the X–register rotates into the T–register, the contents of the T–register rotate into the Z–register, etc. Notice that only the centents of the registers are rolled — the registers themselves maintain their positions, and only the X–register's contents are displayed.

Rµ (Roll Up)

The {8(roll up) key has a similar function to 9except that it "rolls" the stack contents upward, one register at a time.

The contents of the X–register rotate into the Y–register; what was in the T–register rotates into the X–register, and so on.
