PH69431: IVPS CONTAIN MOVE THAT INTRODUCES INVALID DATA

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The "MOVE CVIVNMBR OF PVICBLC TO VIVWORK." line of code in the
  IVP job CQIPGM1 initializes SEED, a PIC 9(9)V9(7) USAGE DISPLAY
  data item, to SPACES. This can cause an issue if a client
  compiles the IVP with NUMPROC(PFD) and a high-enough ARCH level
  to use vector instructions.
  

Local fix

• Use
  
  INITIALIZE VIVWORK
  
  instead of
  
  MOVE CVIVNMBR OF PVICBLC TO VIVWORK

  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF                       *
  ****************************************************************
  The MOVE statement as written moves SPACES to all data items in
  VIVWORK, causing SEED, a PIC 9(9)V9(7) USAGE DISPLAY data item,
  to contain invalid data. An instruction generated at ARCH(14)
  or above when NUMPROC(PFD) is specified, abends when using this
  invalid data.
  

Problem conclusion

• IVP program CQIIVPS1 was changed, replacing "MOVE CVIVNMBR OF
  PVICBLC TO VIVWORK" with "INITIALIZE VIVWORK" to avoid creating
  an invalid data situation.
