Processing details
■SORT
• Sorts (rearranges data) BIN 16-bit data n points from (S1) in ascending or descending order. Sort order is designated by the
ON/OFF status of SM703:
• 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 (S2). (Decimal fractions are rounded up.) When the value of (S2) is
increased, the number of scans until completion of the sort is reduced, but the amount of time per scan is lengthened.
data blocks compared at one execution designated by (S2). (Decimal fractions are rounded up.) When the value of (S2) is
increased, the number of scans until completion of the sort is reduced, but the amount of time per scan is lengthened.
(S1): Head device number in the table to be sorted (BIN 16/32 bits)

n:
Number of data blocks to be sorted (BIN 16 bits)
(S2): Number of data blocks to be compared in one sort operation (BIN 16 bits)
(D1): Number of the bit device to be turned ON at the completion of the sort operation (bits)
(D2): Device reserved for the system (BIN 16 bits)
(D1): Number of the bit device to be turned ON at the completion of the sort operation (bits)
