1
records with m
2
fields having a start or head
address of S. Then the data in field nis sorted in to
numerical order while retaining each individual
numerical order while retaining each individual
records integrity. The resulting (new) data table is stored from destination device D.
Points to note:
a) When a sort occurs each record is sorted in to ascending order based on the data in the
selected sort field n.
b) The source (S) and destination (D) areas can be the same BUT if the areas are chosen to
be different, there should be no overlap between the areas occupied by the tables.
c) Once the SORT operation has been completed the ‘Operation Complete Flag’ M8029 is
turned ON. For the complete sort of a data table the SORT instruction will be processed
m1times.
m1times.
d) During a SORT operation, the data in the SORT table must not be changed. If the data is
changed, this may result in an incorrectly sorted table.
e) The SORT instruction may only be used ONCE in a program.
From the example instruction and the ‘data table’ below left, the following data manipulation
