 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' SUBCODES X'18' and X'38'.
 LOCATED BY : THE POINTER TO THIS AREA IS CONTAINED IN THE RX
              REGISTER OF THE DIAGNOSE X'64' SUBCODE X'18'
              AND X'38' FUNCTIONS.
 CREATED BY : THE RX REGISTER OF DIAGNOSE X'64' SUBCODES
              X'18' and X'38' IS SETUP BY THE USER TO POINT
              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.
