     NAME       : HCPSAMBK
     DESCRIPTION: SNAPPED AREA'S MAP BLOCK
     DSECT      : SAMBK
     FUNCTION   : A SAMBK CONTAINS THE POINTER AND CONTROL INFORMATION
                  TO ACCESS THE SNAPPED SAVERAREAS AND SNAPPED DATA AREAS
                  IN THE SOFT ABEND DUMP FILE.
     LOCATED BY : DFISAMBK FIELD IN HCPDFIR
     UTILIZED BY  THE SOFT ABEND PROCESSOR (HCPABN)
     DELETED BY : N/A
     SERIALIZED : THE SOFT ABEND LOCK (HCPABNLK) WHEN A SOFT ABEND
                  DUMP IS OCCURRING.
