Example 5: Creating a Partitioned, Key-Sequenced File
This example shows how to create a key-sequenced file that will span six partitions. The record
format is the same as in “Example 1: Creating a Key-Sequenced File” (page 76)

The file is to reside on six volumes and be partitioned in this manner:
$PART0
$PART1
$PART2
$PART3
$PART4
$PART5

NOTE: If the file is an enhanced key-sequenced file (with more than 16 partitions), then the
primary partition is reserved for internal configuration information and does not contain data. In
this case, you must set the partition key value for the first secondary partition to zero.
To create the file with FUP, include SET PART commands to describe the partitioning.
