program and utility interfaces to VSAM, partitioned, sequential, and direct access
types.
DFP also provides the Interactive Storage Management Facility (ISMF) which
allows the definition and maintenance of storage management policies
interactively. It is designed to be used by both storage administrators and end
users.

masking criteria. This panel is selected from the ISPF/PDF primary menu
