Each text data page contains user text and image data, and a section known as the text and image pages stats area (TIPSA).
The TIPSA contains information about the text and image data that is contained on the current text page. For instance, in a server configured for multibyte character sets, the TIPSA contains the number of whole characters that are on the current page.
