34 Transfer (s)+1 written sequentially to (d) by SFWR instruction, shift up each point (n)-1 by one word from (s)+1. The number of stored data of (s) subtracts one.
35
36 The content of (s)+1 is transferred (read) to (d). At the same time, the content of the pointer (s) decreases, and the data is shifted up by 1 word each. (In the continuous execution instruction SFRD, each operation cycle will shift, so the pulse execution instruction SFRDP should be used for programming).

49 In the case of continuous execution (SFRD) instructions, each scan time (operation cycle) will be read sequentially, but the content of (s) + (n) would not change. When the pointer (s) is 0, it would become no processing, and the content of (d) would not change.

After that, the data will be filled in sequentially from the right, and the number of data storage points is displayed by the content of the pointer (d).
