In the first example rung above, an Indirect Move function copies the constant 5 into a register pointed to by R1. During one program scan, R1 might point to register R20. In another scan, it might point to register R21.

The second example rung has no conditional logic; each program scan, it copies the content of register R2 to a register which is pointed to by register R3.
