Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• APAR PI58857/PTF UI37372 introduces a memory corruption
  problem.  IGZXNE2N writes past the end of the result temp by 1
  byte, which ends up corrupting the address temp that follows
  it.  Errors that may occur are S0C4-04 or IGZ0064S.  The
  compiler will be corrected.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.1 compiling and  *
  *                 running programs containing MOVE statements  *
  *                 satisfying the following conditions:         *
  *                 1. The sender of the MOVE statement is       *
  *                 numeric-edited and the receiver is numeric   *
  *                 or numeric-edited.                           *
  *                                                              *
  *                 2. The PIC string for the sender and         *
  *                 receiver data items do not both indicate a   *
  *                 signed data item.                            *
  *                                                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Possible 0C4 ABEND at runtime in the    *
  *                      COBOL program (S0C4).                   *
  *                                                              *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  *                                                              *
  ****************************************************************
  A temp used to hold the result of de-editing a numeric-edited
  data item was one byte too short in certain situations.
  

Problem conclusion

• The compiler was updated to ensure that the length of temps
  used for de-editing are sufficiently long in all scenarios.
