The Pool Definition screen is used to define, display and modify pool parameters. Pool parameters specify logical groups of volumes. This screen can be entered directly from the entry panel or from the Pool List screen. Update of parameters is not permitted in Browse mode.
The pool parameters may fill more than one screen.

FILL IN POOL DEFINITION. CMDS: EDIT, SHPF 12.58.05
The pool parameters are divided into the following basic groups:
The groups are separated by a delimiter line.
To delete a parameter on the screen, simply erase it (press the EOF key, or blank it out). If additional operations are required, Control-M/Tape issues appropriate instructions.
The Pool Definition screen can also be edited using ISPF-like editing commands (such as copy, move, repeat, after, before) in the Control-M/Tape Edit environment. For additional information, see Editing Rule Definitions in the IOA Edit Environment.
Pool definitions are automatically saved in a PDS member (a Pool table) that can be edited using a standard editor such as the ISPF Edit facility. Pools originally defined using a standard editor can also be displayed and edited in the Online Pool Definition screen. The pool table name is defined at time of installation (Default: $$POOL).
The Pool Definition screen can be exited in various ways. The most common is to press END (PF03/PF15). For more information, see Exiting the Pool Definition Facility.
To immediately implement newly defined or modified Pool definitions, reload them through procedure CTTINIT. For more information, see "Procedure CTTINIT" in the Control-M/Tape chapter of the INCONTROL for z/OS Administrator Guide.
Note: The parameters marked with the symbol M can have many occurrences. Whenever you fill the last occurrence of the parameter on the screen, Control-M/Tape adds a new empty occurrence of that parameter that you can fill in. The only limit to the number of occurrences is the region size available for the application.
