Running a Permutation Sort
Running a Permutation Sort
The output records from a permutation sort consist of the input record sequence
numbers, in the order the records would be in if they were sorted according to the
specified key fields. The following commands direct FastSort to reorder the records in
PLANTS1 and PLANTS2 using the same key fields and to write only the sequence
numbers to SORTOUT:
19> SORT

The following example shows the contents of the SORTOUT file after the sort run using
the FUP COPY command. Note that FUP displays the record sequence numbers in
octal format.
