SDMBK Prolog

 NAME       : HCPSDMBK
 DESCRIPTION: SNAP DATA MAP BLOCK
 DSECT      : SDMBK
 FUNCTION   : A SDMBK DESCRIBES THE SNAP LIST DATA THAT IS CONTAINED
              IN THE SNAP BUFFERS OF THE SOFT ABEND DUMP. INCLUDED
              IN THE MAP IS A COPY OF THE PARAMETER LIST THAT WAS
              PASSED TO THE SOFT ABEND PROCESSOR.
 LOCATED BY : SAMSDMBK FIELD IN HCPSAMBK
 UTILIZED BY  THE SOFT ABEND PROCESSOR (HCPABN)
 DELETED BY : N/A
 SERIALIZED : THE SOFT ABEND LOCK (HCPABNLK)
