Running a Record Sort
A record sort reorders input records according to the values of one or more key fields.
The following commands tell FastSort to reorder the records from PLANTS1 and
PLANTS2 by using the values in three key fields and to write the records to the file
named SORTOUT:

The REMOVEDUPS parameter tells FastSort to remove any record that has the same
values in all the key fields as a previous record. After the sort run, the SORTOUT file
contains all the input records in sorted order, except for two records that have duplicate
key-field values. FastSort preserves only the first occurrence of these records. The
following example shows the contents of the SORTOUT file.
