Once data has been stored in a table, either of the following two page search modes can be used to search the storage area:

• New page allocation mode
  When the final page of a used segment becomes full, a new unused segment is allocated. If no unused pages remain in the RDAREA, free space to store the data is searched for in used pages from the beginning of the used segments.
  
• Free page reuse mode
  When the final page of a used segment becomes full, free space is searched for in the used pages of the used segments before any unused segments are allocated. The search start position is then remembered for next search, and the subsequent search for free space begins from that point.
