     NAME       : SLHREC
     DESCRIPTION: SUBCHANNEL LOGOUT ERROR RECORD
     DSECT      : SLHREC
     FUNCTION   : CONTAINS SUBCHANNEL LOGOUT DATA FOR ERROR
                  RECORDING.
     LOCATED BY : GPR6 IN HCPIOE.  THE ADDRESS IS PASSED TO
                  HCPREC IN GPR1, AND HCPVER USES GPR9 TO
                  ADDRESS THIS BLOCK.
     CREATED BY : HCPRFC
     DELETED BY : HCPIOE AFTER HCPREC HAS COPIED IT INTO
                  A GSDBK.
