     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)
