 CSETTPTR Prolog 

 Name       : CSETTPTR
 Description: Layout of the VM/CSE Trace Table Pointers.
 DSECT      : CSETTPTR
 Notes      : This DSECT is mapped on the HCPSYSTT table in HCPSYS.
              The CSETRACE MACRO in HCPSYS defines the size of the VM/CSE trace
              table in 4K pages. The first part of the first page is used to trace
              Spool Synchronization Requests. The second part of the first page,
              starting at offset ITTLNSYN, and all of each subsequent page, is used t trace
              requests associated with Diagnose X'F0' Spool requests.
