Changing these points may cause an error code to be returned (Error code: 4100).
(6) If the value of n is changed during the execution of the SORT instruction, the sort will be conducted in accordance with
the number of sort data blocks after the change.
(7) If the execution command is turned OFF during the execution of the SORT instruction, the sort is suspended. The sort
resumes from the beginning when the execution command is turned ON again.
(8) To execute another sort operation immediately after the completion of the previous sort, turn OFF the execution
command once, then turn it ON.
DSORT

Sort order is designated by the ON/OFF status of SM703:
• When SM703 is OFF : Ascending order sort
• When SM703 is ON : Descending order sort

(2) Several scans are required for sorts performed by the DSORT instruction. The number of scans executed until
completion is the value obtained by dividing the maximum number of times executed until the completion of the sort by

(3) The maximum number of executions until completion of the sort should be calculated according to the following
equation:
The maximum number of executions until completion
Example
When n 10, the number of executions is obtained as 10
