SORT, DSORT
: Head device number in the table to be sorted (BIN 16/32 bits)
S1
n : Number of data blocks to be sorted (BIN 16 bits)
: Number of data blocks to be compared in one sort operation (BIN 16 bits)
S2
: Number of the bit device to be turned ON at the completion of the sort operation (bits)

Function
SORT
(1) Sorts (rearranges data) BIN 16-bit data n points from
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 SORT 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 the number
of data blocks compared at one execution designated by
increased, the number of scans until completion of the sort is reduced, but the amount of time per scan is lengthened.
(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
of scans until the completion of sort is calculated as 45/2 22.5
(4) The device designated by
ON when the sort is completed. Because the device designated by
of the sort, the user must turn it OFF if required.
