You can split read-only GLOP data into a number of pages, each of which can be overlaid with the current GLOP data in memory. The page to initially map for read-only GLOP data can be specified when you call DBCExtension.GLOP_Add to add the GLOP data or DBCExtension.GLOP_Change to change the GLOP data.
Different external routines can map different pages for read-only GLOP data at the same time.
Read/write or globally modifiable GLOP data can only consist of one page.
For details on the read-only, read/write, and globally modifiable modification attributes, see GLOP Modification Attributes.
