# PD - Size of Page Data Set

This Natural profile and session parameter specifies the maximum number of pages (screens) which can be stored at the same time in the Natural system file (`FUSER`) with the screen-paging utility.

Within a Natural session, the profile parameter `PD` can be overridden by the session parameter `PD`.

Possible settings | `0` or `1 - 255` | Maximum number of pages (screens).
Default setting | `50` |
Dynamic specification | yes |
Specification within session | yes |
Applicable statements | `SET GLOBALS` |
Applicable command | `GLOBALS` |

Notes:

1. If the number of stored screens exceeds the setting of `PD`, wrap-around technique is used for the system file, which means that the oldest page is overwritten.
2. For further information on the screen page utility, see the terminal commands `%E`, `%I`, `%O`, %P and `%S`.
