NAME       : HCPSXOBK
 DESCRIPTION: DIAGNOSE X'64' SEGMENT EXTENDED OUTPUT AREA
 DSECT      : SXODABK
 FUNCTION   : THIS BLOCK WILL MAP THE SEGMENT EXTENDED OUTPUT AREA
              FOR DIAGNOSE X'64' SUBCODES X'18' and X'38'.
 LOCATED BY : THE POINTER TO THIS AREA IS PROVIDED BY THE
              SXIOAREA FIELD OF HCPSXIBK COPY. IT IS A USER SUPPLIED
              AREA THAT MUST BE ON A DOUBLEWORD BOUNDARY AND CANNOT
              CROSS A PAGE BOUNDARY.
 CREATED BY : THE RX REGISTER OF DIAGNOSE X'64' SUBCODES
              X'18' AND X'38' IS SETUP BY THE USER TO POINT
              TO A USER SUPPLIED BUFFER.  WITHIN THAT USER
              SUPPLIED BUFFER, THE USER PROVIDES THE ADDRESS
              OF THIS AREA WITHIN THE SXIOAREA FIELD OF
              HCPSXIBK COPY.
              - THIS BUFFER MUST RESIDE ON A DOUBLEWORD BOUNDARY AND
              CANNOT CROSS A PAGE BOUNDARY.
 DELETED BY : THIS AREA IS USER SUPPLIED AND USER DELETED.
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : The old SXOBK format (with 32-bit wide address
              fields) can only be used by the subcode X'18',
              which can only be used to obtain information on
              below 2G segments/spaces.  The new format (with
              64-bit wide address fields) and corresponding
              subcode X'38' must be used for above 2G DCSSs.
              (However, the new subcode X'38' and format
              can of course be used to obtain information on
              below 2G segments/spaces)
