Reload an NDB from an Unload File

Having unloaded an NDB, you might want to reload it, possibly to restore the NDB to a previous state, or to take it to another system.

It is assumed that the reload is to a new NDB that has been defined with IDCAMS, allocated to your product region, and an NDB created.

For the purposes of the example, only minimal error checking is performed. The sample procedure can be enhanced in many ways. Some of these are:

Allow merging of the unload data into an existing NDB
Display a field selection list and allow field attribute changes, field renaming, and field deletion
Subset data selection, and so on
Using LOAD MODE to greatly speed up the load. This requires use of NDB ALTER to build keys.
