ABWSECT Prolog
Name : DMSABW
Description: Abend Recovery Workspace
DSECT : ABWSECT
Function : Mapping macro which maps system
information when an abnormal termination
occurs. ABWSECT describes the fields used for
saving registers and other data during abend
recovery. V-constants in DMSABE, DMSDBG,
DMSITI, DMSITP, and DMSITS point to the ABWSECT
block.

ABNDPLST is a Dump Address Parameter List used by the AUTODUMP command.
It contains the list of addresses which are to be included within the
VMDUMP. The default plist now dumps 3 locations : DMSNUC, Loader Tables
and the Storage management work area along with the Page Allocation
Table. The addresses of the areas are established during
initialization.
If the ENTIREVM option is specified on the AUTODUMP command ABNDPLST
will be set up to dump the entire virtual machine. In this case ABNDNUM
will be set to 1 and only the first address pair is used. ABNNUCST
remains zero and ABNNUCND is set to VMSIZE-1. Additionally, specifying
the ENTIREVM option will dump all discontiguous saved segments in use
by the virtual machine.
This info is listed under the DIAG X'94' instruction.
