Description
* GENERATE LOAD builds two command files. One contains commands for
unloading data from selected tables into files. The other
contains commands for loading the data in the files back into
tables.
* EXTERNAL or INTERNAL format can be selected and used. Optionally,
you can UPDATE STATISTICS after the LOAD.
* LOAD EXTERNAL requires a prefix for naming description files and a
NULL indicator.
