 NAME       : CRDREC
 DESCRIPTION: CHANNEL REPORT WORD ERROR RECORD
 DSECT      : CRDREC
 FUNCTION   : CRDREC  PROVIDES STATISTICAL DATA FOR ERROR
              RECOVERY AND/OR ERROR RECORDING RELATED TO
              PREVIOUSLY PERFORMED CHANNEL OPERATION THAT
              DID NOT SUCCESSFULLY COMPLETE.
 LOCATED BY : GPR6 IN HCPRFC AND HCPIOE.  THE ADDRESS
              IS PASSED TO HCPREC IN GPR1.
 CREATED BY : HCPRFC
 DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO
              A GSDBK.
