The EDGHSKP EXPROC utility can be run in parallel on multiple systems, but only one copy per system can be run regardless of the volumes that are processed. An optional EXPROC command in the SYSIN file can be used to:

• Request that only a subset of volumes are processed by EXPROC.
• Request that system-managed volumes are not returned to scratch during expiration processing. Instead, for each system-managed volume ready to return to scratch, a control statement is generated for use with the EDGSPLCS utility so that volumes can be scratched later. The control statements are written to the EDGSPLCS DD.
