PARTITION
Partition a table.
This command partitions a table and can optionally generate the Omnidex
environment file entries necessary to index and search the partitioned
table.
 This
command is provided as a convenience but is not required to be used in
order to take advantage of partitioning in an Omnidex application.
The partitioned data will be put into flat files which are stored in
either the same location as the environment file (default) or the location
specified by the IN path clause.
Two files, partition.log and partition.rpt, will be generated detailing
exactly how the partition was created.
Use the REPORT_ONLY option to generate these reports without actually
partitioning the data.
