Processing
Example 1) Taking out the last five characters from the DT0 string to transfer them
to DT20
"B" "A" "E" "D"
"1"
"2"
"3"
8 (No. of characters)
DT0
DT1
DT2
DT3

5 (No. of characters)
Characters to search

Example 2) The number of characters of [S2] is larger than the number of characters
in the string of [S1]
"B" "A" "B" "A"
"C"
3 (No. of characters)

Precautions for programming
● The character data of the [D] area from before performing the operation is overwritten.
● When the number of characters of [S2] is greater than the number of characters in the string
of [S1], the transferal is performed for the number of characters of [S1].
