 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
  TILIZED BY - THE SOFT ABEND PROCESSOR (HCPABN)
 DELETED BY : N/A
 SERIALIZED : THE SOFT ABEND LOCK (HCPABNLK) WHEN A SOFT ABEND
              DUMP IS OCCURRING.
 RELOCATION CONSIDERATIONS : None
