Section 1 record

Edit online

The Section 1 record is not required for mapping the data in the exported file. However, it is useful for determining how to reallocate a data set when a persistent data store file must be reconstructed.

Important: The content in this section was created for and applies to the original persistent data store, referred to as PDS V1. A new PDS version (referred to as PDS V2) now exists. PDS V1 will eventually be deprecated.

Section 1 contains a single data row used to describe information about the source of the data recorded in the export file. The data layout for the record follows.
