     NAME       : HCPSXIBK
     DESCRIPTION: DIAGNOSE X'64' SEGMENT EXTENDED INPUT AREA
     DSECT      : SXIDABK
     FUNCTION   : THIS BLOCK WILL MAP THE SEGMENT EXTENDED INPUT AREA
                  FOR DIAGNOSE X'64' SUBCODE X'18'.
     LOCATED BY : THE POINTER TO THIS AREA IS CONTAINED IN THE RX
                  REGISTER OF THE DIAGNOSE X'64' SUBCODE X'18' FUNCTION.
     CREATED BY : THE RX REGISTER OF DIAGNOSE X'64' SUBCODE X'18' IS
                  SETUP BY THE USER TO POINT TO A USER SUPPLIED BUFFER.
                  - THIS BUFFER HAS A MINIMUM LENGTH OF THREE DOUBLEWORDS.
                  - THIS BUFFER MUST RESIDE ON A DOUBLEWORD BOUNDARY AND
                  CANNOT CROSS A PAGE BOUNDARY.
                  - THE SXIOAREA FIELD DEFINES AN OUTPUT AREA. THIS AREA
                  IS USER SUPPLIED AND MUST RESIDE ON A DOUBLEWORD
                  BOUNDARY AND CANNOT CROSS A PAGE BOUNDARY.
                  THIS AREA IS DEFINED BY THE HCPSXOBK DSECT.
     DELETED BY : THIS AREA IS USER SUPPLIED AND USER DELETED.
