SYSAREA parameter
Parameter type
Keyword, optional
Purpose
Use the SYSAREA (system area) parameter to indicate whether the system should reserve an area on each page of printed output for the security label. The security label represents a security level and categories as defined to RACF®.
Note: When a system area is reserved for a security label,
the system shifts the printed output on each page. You cannot print
output data in the system area.
Reference
For additional information on the system area, refer to PSF for z/OS: Customization and PSF for z/OS: Security Guide.
