 NAME       : HDRREC
 DESCRIPTION: COMMON HEADER FOR ERROR RECORDS
 DSECT      : HDRREC
 FUNCTION   : PROVIDE THE COMMON FORMAT FOR THE HEADER
              PORTION (FIRST 24 BYTES) OF ALL ERROR
              RECORDS.
 LOCATED BY : ANY FIELD WHICH LOCATES ONE OF THE OTHER
              ERROR RECORDS.  THE DEFINITIONS IN HDRREC
              MAY BE USED IN CONJUNCTION WITH OR IN PLACE
              OF THE HEADER OF ANY OTHER ERROR RECORD.
 CREATED BY : ANY MODULE WHICH CREATES ANY OTHER ERROR
              RECORD (AS THE FIRST 24 BYTES OF THAT
              ERROR RECORD).
 DELETED BY : THE FIELDS DEFINED HERE ARE DELETED WITH
              WHATEVER ERROR RECORD THEY ARE CONTAINED IN.
