Valid values are:

• OPT- Allows allocation on EAV. Default.
• NO - Prevents allocation on EAV.

WRKCYL#

Number of cylinders to allocate for Control‑D print plan files.

• Valid range: 1 through 99.

This file is used for print management. Recommended value: 5 (cylinders).

WRKPREF

Data set name prefix of Control‑D print plan files (used for print management). This prefix must be from 1 through 12 characters in length and may include periods. The last character must not be a period.

• Mandatory

Verify that the data set name prefix (WRKPREF) is defined in the site security facility and has an alias defined in the user catalog.

WRKUNIT

Default UNIT for Control‑D print plan files. The unit name must be a valid unit name of from 1 through 8 characters.

If WRKVOL is not specified, the volume to be used for print plan files must be defined in the VATLSTnn member in the SYS1.PARMLIB library with an attribute of STORAGE.

WRKVOL

Default volume serial number for Control‑D print plan files. Only one volume can be specified. The volume serial number must range from 1 through 6 characters.

If this parameter is left blank, print plan files are allocated on volumes with status STORAGE in the specified WRKUNIT.

Print plan files are allocated when a printing mission is executed and are deleted when the printing mission is deleted by the Control‑D New Day procedure.
