Hi Shimon, I looked up HCPXCTBK in the z/VM 5.4 Data Areas and Control Blocks at:
http://www.vm.ibm.com/pubs/cp540/XCTBK.HTML Here is the prologue to the control block: Name : HCPXCTBK Description: CP Exit Control Block DSECT : XCTBK Function : This control block contains information used to control the structure of XITBKs. Located by : SYSCM.SYSEXITS Created by : HCPZXUIN Deleted by : none Since this refers to XITBK, the prologue for it is: Name : HCPXITBK Description: CP Exit Block DSECT : XITBK Function : This control block contains information used to authorize user exit routines to find their entry points. Located by : Radix tTree structure anchored by XCTBK.XCTRADIX. Created by : HCPZXUAD Deleted by : HCPZXUDL (The deletion is only allowed if the XITBK is for a Dynamic Exit that is NOT enabled and is NOT associated at delete time) and can be found at: http://www.vm.ibm.com/pubs/cp540/XITBK.HTML All of the fields in these control blocks are documented at the referenced URLs.

I can find no reference anywhere to why I should need this line (except that it appears once in a sample). Does anyone else have it? May I ask what for? Can I leave it out? Thanks!
