Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V5 and later       *
  *                 releases using COBOL Vendor Interface        *
  *                 routine IGZXAPI function code 8.             *
  ****************************************************************
  * PROBLEM DESCRIPTION: IGZXAPI abends with U4088.              *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  When IGZXAPI function code 8 is called using an LE CAA that
  is different from the one used by the COBOL program, code
  logic in IGZXAPI mixes up the two CAA addresses, causing
  invalid storage access in subsequent processing.

Problem conclusion

• IGZXAPI function code 8 has been fixed to handle the different
  CAA addresses correctly.
  
  A new input field, XCAA8, has been added to parameter
  structure XINFO8 at offset 92. The size of the field is
  4 bytes. When IGZXAPI function code 8 is called using a CAA
  that is different from the one used by the COBOL program, set
  XCAA8 to the CAA of the COBOL program, set R12 to the CAA
  used by the caller of IGZXAPI. Set the length of the
  parameter structure, XLEN8, to 96. Call IGZXAPI function
  code 8 with this modified parameter structure.
  
  This does not affect the usage when IGZXAPI is called using
  the same CAA as the COBOL program. No change is needed for
  those cases.
