Precautions for programming
● When the number of characters of [S3] is larger than the number of characters of the [S1]
string starting from the [S2] position, the transferal is performed for the number of characters
of [S1].
● The [S2] position should be specified by a number counted from low order in sequence,
putting the least significant byte as K0 (Byte 0): 0, 1, 2 and so on.
● When the number of characters in the operation result is larger than the storage area size of
[D], the transferal is performed for the storage area size of [D].
● When specifying with a character constant, the maximum is 256 characters.
● When specifying an empty string for [S1], the result is always 0.
