This chapter describes pools in general. Pools are windows that display objects in the show file.

## Pool objects

Every pool contains pool objects.

Every pool object with content has a brighter frame compared to an empty pool object.

The first pool object tile displays the name of the pool. If the focus is set to a pool, the first pool tile is blue.

_Group pool with focus_

The number in the upper left corner of a pool object is the pool object number.

A pool displays at least a full screen of pool object tiles, for example 127 pool object tiles on screen 2 of a grandMA2 console. If the empty object tiles do not exceed 100, a further page with empty object tiles will be added. In total, there are 9999 object tiles per pool.

**Hint:**\
To expand the group pool for example by 1000 empty pool object tiles, type into the command line:\
\- Store Group 1000 and press Please\
\- Delete Group 1000 and press Please\
The group pool is expanded by empty group pool objects.

For information about the pool object colors see [workspace - colors - system](/grandma2/key_ws_colors_system/).
