 NAME       : HCPSYMPT
 DESCRIPTION: Symbol LOCATE Pointer Block
 DSECT      : SYMPT
 FUNCTION   : The Symbol LOCATE Pointer Blocks are chained from the
              SYMLH.  Each SYMPT controls a set of SYMTB entries.
 LOCATED BY : SYMLHPT1 in SYMLH
              SYMPTFWD in SYMPT
 CREATED BY : HCPCFD
 DELETED BY : None
 REFERENCES : None
 SERIALIZED : Additions or changes to the SYMPT entries and to the
              SYMTB entries requires exclusive control of the
              SYMLHLCK lock.
              Searches of the SYMPT entries and of the SYMTB entries
              requires shared control of the SYMLHLCK lock.
 RELOCATION CONSIDERATIONS : None
