DDSR identifies this command as a DDSR function. DDSR causes the release of the physical storage space associated with:
∙

Expired files
A total volume
A range of cylinders
A specified file
This function ensures that all space releases done on the VSE system (normally through deletes) result in space releases in the RVA subsystem. Figure 14 shows the syntax of the IXFP DDSR command.

4.2.1 Expired Files
DDSR, when specified without any additional parameters, deletes the VTOC entries and all physical space for all expired nonsecured files residing on VSE managed RVA devices. These extents are freed up and become part of free space.
To illustrate, we use two volumes: PATEV1 and PATEV3. The device addresses of these volumes are 80E and 80F, respectively. To delete all
