NAME : HCPDGNBK
DESCRIPTION: Diagnose Table Entry Block
DSECT : DGNBK
FUNCTION : The Diagnose Table Entry Blocks are used to control and
to locate the modules that are called when a virtual
machine has executed a diagnose instruction.
LOCATED BY : Diagnose radix tree, anchored in the Diagnose Control
Header, which is pointed to by SYSDIAGS in SYSCM.
DGNOVRDE if an MODIFY operation has been done but
no MODIFY RESET has been done.
CREATED BY : HCPDDG as a result of DEFINE DIAGNOSE command or
configuration statement.
HCPHVB assembly during SYSGEN.
HCPHVAAD adds a new DGNBK (created by someone else)
to the DGNBK radix tree
HCPDDGOV as a result of MODIFY processing
DELETED BY : None
REFERENCES : HCPCLASS - Privilege class definitions
The DGNBK begins with storage that is mapped by the
ICRBK DSECT. This storage is followed by the real
DGNBK fields that define and control the diagnose code.
SERIALIZED : Changes to the contents of DGNBKs are typically done
by diagnose A0 and by User Class Restructure, and
under the SYSLCKC4 lock.
RELOCATION CONSIDERATIONS : None
