Precautions for programming
● It must be noted that, since the time for data comparison increases in proportion to the
square of the number of data, the sorting process can take a long time when there is a large
amount of data to be sorted.
● During sort execution, data in [S1] to [S2] are sorted in sequence according to the sort
conditions.
● The end position of the sort range is the device that contains [S2].
Example) When the operation unit is 32 bits, the sort range is the same whether a device
number of higher level or lower level is specified.
