Outline of operation
This instruction takes out the characters for the number specified for [S2] from the right side
(end of the character data) of the string specified by [S1], and stores them as string data in
the device whose address is specified by [D].
The number of bytes of string data that are taken out is stored in [D+1].
For both [S1] and [D], the size of the starting storage area must be set by using the user
program before an instruction is executed.
Processing
Example 1) Taking out the last five characters "DE123" from the string "ABCDE123"
to store them as string data with storage area in DT20 and later
[S1]...DT0 [S2]...U5 [S2]...DT20
